Pottrsquos Disease

Dexter Jay B FloresBSN ndash 3 UNEP

Pottrsquos diseasebull This entity was first described by Percivall

Pott He noted this as a painful kyphotic deformity of the spine associated with paraplegia

bull Tuberculosis of the spine is one of the oldest diseases afflicting humans Evidences of spinal tuberculosis have been found in Egyptian mummies dating back to 3400 BC

bull One fifth of TB population is in India

bull Three percent are suffering from skeletal TB

bull 50 of these suffer from spinal lesion and almost 50 are from pediatric group An estimated 2 million or more patients have active spinal tuberculosis

bull Every day 1000 die of tuberculosis in India

Pathophysiology

bull Pott disease is usually secondary to an extraspinal source of infection

bull The basic lesion is a combination of osteomyelitis and arthritis

bull The area usually affected is the anterior aspect of the vertebral body adjacent to the subchondral plate

bull Tuberculosis may spread from that area to adjacent intervertebral disks

In adults disk disease is secondary to the spread of infection from the vertebral body

In children because the disk is vascularized it can be a primary site

bull Progressive bone destruction leads to vertebral collapse and kyphosis The spinal canal can be narrowed by abscesses granulation tissue or direct dural invasion This leads to spinal cord compression and neurologic deficits

bull Kyphotic deformity occurs as a consequence of collapse in the anterior spine Lesions in the thoracic spine have a greater tendency for kyphosis than those in the lumbar spine

bull The collapse is minimal in cervical spine because most of the body weight is borne through the articular processes

bull Healing takes place by gradual fibrosis and calcification of the granulmatous tuberculous tissue Eventually the fibrous tissue is ossified with resulting bony ankylosis of the collapsed vertebrae

bull Paravertebral abscess formation occurs in almost every case With collapse of the vertebral body tuberculous granulation tissue caseous matter and necrotic bone and bone marrow are extruded through the bony cortex and accumulate beneath the anterior longitudinal ligament

bull These cold abscesses gravitate along the fascial planes and present externally at some distance from the site of the original lesion

bull In the lumbar region the abscess gravitates along the psoas fascial sheath and usually points into the groin just below the inguinal ligament

bull In the thoracic region the longitudinal ligaments limit the abscess which is seen in the radiogram as a fusiform radiopaque shadow at or just below the level of the involved vertebra

bull Thoracic abscess may reach the anterior chest wall in the parasternal area by tracking via the intercostal vessels

The lesion could bebull Florid - invasive and destructive lesion

bull Non destructive - lesion suspected clinically but identifiable by modern investigations like CT scan or MRI

bull Encysted disease

bull Carries sicca

bull Hypertrophied

bull Periosteal lesion

bull Recently two distinct patterns of spinal TB can be identified the classic form called spondylodiscitis (SPD) a

bull atypical form characterized by spondylitis without disk involvement (SPwD)

bull SPwD seems to be the most common pattern of spinal TB

Anatomically the lesion could be 1 Paradiscal - destruction of

adjacent end plates and diminution of disc space

2 Appendeceal (Posterior) - involvement of pedicles laminae spinous process

3 Central - Cystic or lytic concertina collapse

4 Anterior ndashlongitudinal lig Aneurysmal phenomenon

5 Synovitis in post facet

History

bull Presentation depends on the following ndash Stage of disease

ndash Site

ndash Presence of complications such as neurologic deficits abscesses or sinus tracts

bull The reported average duration of symptoms at the time of diagnosis is 3-4 months

bull Back pain is the earliest and most common symptom ndash Patients have usually had back pain for weeks prior to

presentation

ndash Pain can be spinal or radicular

bull Constitutional symptoms include fever and weight loss

bull Neurologic abnormalities occur in 50 of cases and can include spinal cord compression with paraplegia paresis impaired sensation nerve root pain or cauda equina syndrome

bull Cervical spine tuberculosis is a less common presentation is characterized by pain and stiffness

Patients with lower cervical spine disease can present with dysphagia or stridor

Symptoms can also include torticollis hoarseness and neurologic deficits

bull The clinical presentation of spinal tuberculosis in patients infected with the human immunodeficiency virus (HIV) is similar to that of patients who are HIV negative however the relative proportion of individuals who are HIV positive seems to be higher

Natural course of disease

bull 53 died within 10 yrs of onsetbull Early stage of healingndash focus surrounded by

sclerotic bone Ivory vertebrabull Early radiological sign of healingndash sharpening of

fuzzy paradiscal margins amp reappearance and minrralization of tuberculae

bull Several vertebrae destroyedndash fibrous tissuebull Disc space destroyed bony ankylosisbone

block formation

Lab Studies

bull Tuberculin skin test (purified protein derivative [PPD]) demonstrates a positive finding in 84-95 of patients who are nonndashHIV-positive

bull Erythrocyte sedimentation rate (ESR) may be markedly elevated

bull The enzyme-linked immunosorbent assay (ELISA) has a reported sensitivity of 60 to 80 per cent

bull The polymerase chain reaction bull A brucella complement fixation test

bull IFN- Release Assays (IGRAs)

bull Recently two in vitro assays that measure T cell release of IFN- in response to stimulation with the highly tuberculosis-specific antigens ESAT-6 and CFP-10 have become commercially available

bull Microbiology studies to confirm diagnosis Obtain bone tissue or abscess samples to stain for acid-fast bacilli (AFB) and isolate organisms for culture and susceptibility CT-guided procedures can be used to guide percutaneous sampling of affected bone or soft tissue structures These study findings may be positive in only about 50 of the cases

X Ray appearances

bull Lytic destruction of anterior portion of vertebral body bull Increased anterior wedging bull Collapse of vertebral body bull Reactive sclerosis on a progressive lytic process bull Enlarged psoas shadow with or without calcificationbull Vertebral end plates are osteoporotic bull Intervertebral disks may be shrunk or destroyed bull Vertebral bodies show variable degrees of destruction bull Fusiform paravertebral shadows suggest abscess

CT scanning

bull CT scanning provides much better bony detail of irregular lytic lesions sclerosis disk collapse and disruption of bone circumference

bull Low-contrast resolution provides a better assessment of soft tissue particularly in epidural and paraspinal areas

bull It detects early lesions and is more effective for defining the shape and calcification of soft tissue abscesses

bull In contrast to pyogenic disease calcification is common in tuberculous lesions

MRI bull MRI is the criterion standard for evaluating disk

space infection and osteomyelitis of the spine bull MRI findings useful to differentiate tuberculous

spondylitis from pyogenic spondylitis include thin and smooth enhancement of the abscess wall and well-defined paraspinal abnormal signal

whereas thick and irregular enhancement of abscess wall and ill-defined paraspinal abnormal signal are suggestive of pyogenic spondylitis

bull contrast-enhanced MRI appears to be important in the differentiation of these two types of spondylitis

GROUP A_-Early onset - This comes up in active stage of the disease within first 2 years

Compressive Agents are inflammatory edema granulation abscess casseous material sequestra and rarely ischaemic lesion

GROUP B -Late onset- Usually after 2 years of onset of the disease ndash due to recurrence or by mechanical pressure This can be better divided into

paraplegia with active disease and with healed disease

Active disease - Caseous material debris sequestrated disc or bone internal gibbus stenosis and deformity can cause compression

Healed disease - Usually internal gibbus and acute kyphotic deformity can also give late onset paraplegia Usually there is a continuous traction compression leading to paraplegia

bull Healing takes place by gradual fibrosis and calcification of the granulmatous tuberculous tissue Eventually the fibrous tissue is ossified with resulting bony ankylosis of the collapsed vertebrae

bull Paravertebral abscess formation occurs in almost every case With collapse of the vertebral body tuberculous granulation tissue caseous matter and necrotic bone and bone marrow are extruded through the bony cortex and accumulate beneath the anterior longitudinal ligament

bull These cold abscesses gravitate along the fascial planes and present externally at some distance from the site of the original lesion

bull In the lumbar region the abscess gravitates along the psoas fascial sheath and usually points into the groin just below the inguinal ligament

bull In the thoracic region the longitudinal ligaments limit the abscess which is seen in the radiogram as a fusiform radiopaque shadow at or just below the level of the involved vertebra

ndash Site

ndash Presence of complications such as neurologic deficits abscesses or sinus tracts

bull The reported average duration of symptoms at the time of diagnosis is 3-4 months

bull Back pain is the earliest and most common symptom ndash Patients have usually had back pain for weeks prior to

presentation

ndash Pain can be spinal or radicular

bull Constitutional symptoms include fever and weight loss

bull Neurologic abnormalities occur in 50 of cases and can include spinal cord compression with paraplegia paresis impaired sensation nerve root pain or cauda equina syndrome

bull Cervical spine tuberculosis is a less common presentation is characterized by pain and stiffness

Patients with lower cervical spine disease can present with dysphagia or stridor

Symptoms can also include torticollis hoarseness and neurologic deficits

bull The clinical presentation of spinal tuberculosis in patients infected with the human immunodeficiency virus (HIV) is similar to that of patients who are HIV negative however the relative proportion of individuals who are HIV positive seems to be higher

CT scanning

bull CT scanning provides much better bony detail of irregular lytic lesions sclerosis disk collapse and disruption of bone circumference

bull Low-contrast resolution provides a better assessment of soft tissue particularly in epidural and paraspinal areas

bull It detects early lesions and is more effective for defining the shape and calcification of soft tissue abscesses

bull In contrast to pyogenic disease calcification is common in tuberculous lesions

MRI bull MRI is the criterion standard for evaluating disk

space infection and osteomyelitis of the spine bull MRI findings useful to differentiate tuberculous

spondylitis from pyogenic spondylitis include thin and smooth enhancement of the abscess wall and well-defined paraspinal abnormal signal

whereas thick and irregular enhancement of abscess wall and ill-defined paraspinal abnormal signal are suggestive of pyogenic spondylitis

Pathophysiology

bull Pott disease is usually secondary to an extraspinal source of infection

bull The basic lesion is a combination of osteomyelitis and arthritis

bull The area usually affected is the anterior aspect of the vertebral body adjacent to the subchondral plate

bull Tuberculosis may spread from that area to adjacent intervertebral disks

In adults disk disease is secondary to the spread of infection from the vertebral body

In children because the disk is vascularized it can be a primary site

bull Progressive bone destruction leads to vertebral collapse and kyphosis The spinal canal can be narrowed by abscesses granulation tissue or direct dural invasion This leads to spinal cord compression and neurologic deficits

bull Progressive bone destruction leads to vertebral collapse and kyphosis The spinal canal can be narrowed by abscesses granulation tissue or direct dural invasion This leads to spinal cord compression and neurologic deficits

bull Kyphotic deformity occurs as a consequence of collapse in the anterior spine Lesions in the thoracic spine have a greater tendency for kyphosis than those in the lumbar spine

bull The collapse is minimal in cervical spine because most of the body weight is borne through the articular processes

bull Healing takes place by gradual fibrosis and calcification of the granulmatous tuberculous tissue Eventually the fibrous tissue is ossified with resulting bony ankylosis of the collapsed vertebrae

bull Paravertebral abscess formation occurs in almost every case With collapse of the vertebral body tuberculous granulation tissue caseous matter and necrotic bone and bone marrow are extruded through the bony cortex and accumulate beneath the anterior longitudinal ligament

bull These cold abscesses gravitate along the fascial planes and present externally at some distance from the site of the original lesion

bull In the lumbar region the abscess gravitates along the psoas fascial sheath and usually points into the groin just below the inguinal ligament

bull In the thoracic region the longitudinal ligaments limit the abscess which is seen in the radiogram as a fusiform radiopaque shadow at or just below the level of the involved vertebra

bull Thoracic abscess may reach the anterior chest wall in the parasternal area by tracking via the intercostal vessels

bull Recently two distinct patterns of spinal TB can be identified the classic form called spondylodiscitis (SPD) a

bull atypical form characterized by spondylitis without disk involvement (SPwD)

bull SPwD seems to be the most common pattern of spinal TB

Anatomically the lesion could be 1 Paradiscal - destruction of

adjacent end plates and diminution of disc space

2 Appendeceal (Posterior) - involvement of pedicles laminae spinous process

3 Central - Cystic or lytic concertina collapse

bull Periosteal lesion

bull Recently two distinct patterns of spinal TB can be identified the classic form called spondylodiscitis (SPD) a

bull atypical form characterized by spondylitis without disk involvement (SPwD)

bull SPwD seems to be the most common pattern of spinal TB

Anatomically the lesion could be 1 Paradiscal - destruction of

adjacent end plates and diminution of disc space

2 Appendeceal (Posterior) - involvement of pedicles laminae spinous process

3 Central - Cystic or lytic concertina collapse

4 Anterior ndashlongitudinal lig Aneurysmal phenomenon

History

bull Presentation depends on the following ndash Stage of disease

ndash Site

ndash Presence of complications such as neurologic deficits abscesses or sinus tracts

bull The reported average duration of symptoms at the time of diagnosis is 3-4 months

bull Back pain is the earliest and most common symptom ndash Patients have usually had back pain for weeks prior to

presentation

ndash Pain can be spinal or radicular

bull Constitutional symptoms include fever and weight loss

bull Neurologic abnormalities occur in 50 of cases and can include spinal cord compression with paraplegia paresis impaired sensation nerve root pain or cauda equina syndrome

bull Cervical spine tuberculosis is a less common presentation is characterized by pain and stiffness

Patients with lower cervical spine disease can present with dysphagia or stridor

Symptoms can also include torticollis hoarseness and neurologic deficits

bull The clinical presentation of spinal tuberculosis in patients infected with the human immunodeficiency virus (HIV) is similar to that of patients who are HIV negative however the relative proportion of individuals who are HIV positive seems to be higher

Natural course of disease

bull 53 died within 10 yrs of onsetbull Early stage of healingndash focus surrounded by

sclerotic bone Ivory vertebrabull Early radiological sign of healingndash sharpening of

fuzzy paradiscal margins amp reappearance and minrralization of tuberculae

bull Several vertebrae destroyedndash fibrous tissuebull Disc space destroyed bony ankylosisbone

block formation

Lab Studies

bull Tuberculin skin test (purified protein derivative [PPD]) demonstrates a positive finding in 84-95 of patients who are nonndashHIV-positive

bull Erythrocyte sedimentation rate (ESR) may be markedly elevated

bull The enzyme-linked immunosorbent assay (ELISA) has a reported sensitivity of 60 to 80 per cent

bull The polymerase chain reaction bull A brucella complement fixation test

bull IFN- Release Assays (IGRAs)

bull Recently two in vitro assays that measure T cell release of IFN- in response to stimulation with the highly tuberculosis-specific antigens ESAT-6 and CFP-10 have become commercially available

bull Microbiology studies to confirm diagnosis Obtain bone tissue or abscess samples to stain for acid-fast bacilli (AFB) and isolate organisms for culture and susceptibility CT-guided procedures can be used to guide percutaneous sampling of affected bone or soft tissue structures These study findings may be positive in only about 50 of the cases

CT scanning

bull CT scanning provides much better bony detail of irregular lytic lesions sclerosis disk collapse and disruption of bone circumference

bull Low-contrast resolution provides a better assessment of soft tissue particularly in epidural and paraspinal areas

bull It detects early lesions and is more effective for defining the shape and calcification of soft tissue abscesses

bull In contrast to pyogenic disease calcification is common in tuberculous lesions

MRI bull MRI is the criterion standard for evaluating disk

space infection and osteomyelitis of the spine bull MRI findings useful to differentiate tuberculous

spondylitis from pyogenic spondylitis include thin and smooth enhancement of the abscess wall and well-defined paraspinal abnormal signal

whereas thick and irregular enhancement of abscess wall and ill-defined paraspinal abnormal signal are suggestive of pyogenic spondylitis

bull contrast-enhanced MRI appears to be important in the differentiation of these two types of spondylitis

Anatomically the lesion could be 1 Paradiscal - destruction of

adjacent end plates and diminution of disc space

2 Appendeceal (Posterior) - involvement of pedicles laminae spinous process

3 Central - Cystic or lytic concertina collapse

4 Anterior ndashlongitudinal lig Aneurysmal phenomenon

5 Synovitis in post facet

History

bull Presentation depends on the following ndash Stage of disease

ndash Site

ndash Presence of complications such as neurologic deficits abscesses or sinus tracts

bull The reported average duration of symptoms at the time of diagnosis is 3-4 months

bull Back pain is the earliest and most common symptom ndash Patients have usually had back pain for weeks prior to

presentation

ndash Pain can be spinal or radicular

bull Constitutional symptoms include fever and weight loss

bull Neurologic abnormalities occur in 50 of cases and can include spinal cord compression with paraplegia paresis impaired sensation nerve root pain or cauda equina syndrome

bull Cervical spine tuberculosis is a less common presentation is characterized by pain and stiffness

Patients with lower cervical spine disease can present with dysphagia or stridor

Symptoms can also include torticollis hoarseness and neurologic deficits

bull The clinical presentation of spinal tuberculosis in patients infected with the human immunodeficiency virus (HIV) is similar to that of patients who are HIV negative however the relative proportion of individuals who are HIV positive seems to be higher

Natural course of disease

bull 53 died within 10 yrs of onsetbull Early stage of healingndash focus surrounded by

sclerotic bone Ivory vertebrabull Early radiological sign of healingndash sharpening of

fuzzy paradiscal margins amp reappearance and minrralization of tuberculae

bull Several vertebrae destroyedndash fibrous tissuebull Disc space destroyed bony ankylosisbone

block formation

Lab Studies

bull Tuberculin skin test (purified protein derivative [PPD]) demonstrates a positive finding in 84-95 of patients who are nonndashHIV-positive

bull Erythrocyte sedimentation rate (ESR) may be markedly elevated

bull The enzyme-linked immunosorbent assay (ELISA) has a reported sensitivity of 60 to 80 per cent

bull The polymerase chain reaction bull A brucella complement fixation test

bull IFN- Release Assays (IGRAs)

bull Recently two in vitro assays that measure T cell release of IFN- in response to stimulation with the highly tuberculosis-specific antigens ESAT-6 and CFP-10 have become commercially available

bull Microbiology studies to confirm diagnosis Obtain bone tissue or abscess samples to stain for acid-fast bacilli (AFB) and isolate organisms for culture and susceptibility CT-guided procedures can be used to guide percutaneous sampling of affected bone or soft tissue structures These study findings may be positive in only about 50 of the cases

CT scanning

bull CT scanning provides much better bony detail of irregular lytic lesions sclerosis disk collapse and disruption of bone circumference

bull Low-contrast resolution provides a better assessment of soft tissue particularly in epidural and paraspinal areas

bull It detects early lesions and is more effective for defining the shape and calcification of soft tissue abscesses

bull In contrast to pyogenic disease calcification is common in tuberculous lesions

MRI bull MRI is the criterion standard for evaluating disk

space infection and osteomyelitis of the spine bull MRI findings useful to differentiate tuberculous

spondylitis from pyogenic spondylitis include thin and smooth enhancement of the abscess wall and well-defined paraspinal abnormal signal

whereas thick and irregular enhancement of abscess wall and ill-defined paraspinal abnormal signal are suggestive of pyogenic spondylitis

bull Recently two in vitro assays that measure T cell release of IFN- in response to stimulation with the highly tuberculosis-specific antigens ESAT-6 and CFP-10 have become commercially available

bull Microbiology studies to confirm diagnosis Obtain bone tissue or abscess samples to stain for acid-fast bacilli (AFB) and isolate organisms for culture and susceptibility CT-guided procedures can be used to guide percutaneous sampling of affected bone or soft tissue structures These study findings may be positive in only about 50 of the cases

CT scanning

bull CT scanning provides much better bony detail of irregular lytic lesions sclerosis disk collapse and disruption of bone circumference

bull Low-contrast resolution provides a better assessment of soft tissue particularly in epidural and paraspinal areas

bull It detects early lesions and is more effective for defining the shape and calcification of soft tissue abscesses

bull In contrast to pyogenic disease calcification is common in tuberculous lesions

MRI bull MRI is the criterion standard for evaluating disk

space infection and osteomyelitis of the spine bull MRI findings useful to differentiate tuberculous

spondylitis from pyogenic spondylitis include thin and smooth enhancement of the abscess wall and well-defined paraspinal abnormal signal

whereas thick and irregular enhancement of abscess wall and ill-defined paraspinal abnormal signal are suggestive of pyogenic spondylitis

CT scanning

bull CT scanning provides much better bony detail of irregular lytic lesions sclerosis disk collapse and disruption of bone circumference

bull Low-contrast resolution provides a better assessment of soft tissue particularly in epidural and paraspinal areas

bull It detects early lesions and is more effective for defining the shape and calcification of soft tissue abscesses

bull In contrast to pyogenic disease calcification is common in tuberculous lesions

MRI bull MRI is the criterion standard for evaluating disk

space infection and osteomyelitis of the spine bull MRI findings useful to differentiate tuberculous

spondylitis from pyogenic spondylitis include thin and smooth enhancement of the abscess wall and well-defined paraspinal abnormal signal

whereas thick and irregular enhancement of abscess wall and ill-defined paraspinal abnormal signal are suggestive of pyogenic spondylitis

GROUP B -Late onset- Usually after 2 years of onset of the disease ndash due to recurrence or by mechanical pressure This can be better divided into

paraplegia with active disease and with healed disease

Active disease - Caseous material debris sequestrated disc or bone internal gibbus stenosis and deformity can cause compression

Healed disease - Usually internal gibbus and acute kyphotic deformity can also give late onset paraplegia Usually there is a continuous traction compression leading to paraplegia

CT scanning

bull CT scanning provides much better bony detail of irregular lytic lesions sclerosis disk collapse and disruption of bone circumference

bull Low-contrast resolution provides a better assessment of soft tissue particularly in epidural and paraspinal areas

bull It detects early lesions and is more effective for defining the shape and calcification of soft tissue abscesses

bull In contrast to pyogenic disease calcification is common in tuberculous lesions

MRI bull MRI is the criterion standard for evaluating disk

space infection and osteomyelitis of the spine bull MRI findings useful to differentiate tuberculous

spondylitis from pyogenic spondylitis include thin and smooth enhancement of the abscess wall and well-defined paraspinal abnormal signal

Compressive Agents are inflammatory edema granulation abscess casseous material sequestra and rarely ischaemic lesion

GROUP B -Late onset- Usually after 2 years of onset of the disease ndash due to recurrence or by mechanical pressure This can be better divided into

paraplegia with active disease and with healed disease

Active disease - Caseous material debris sequestrated disc or bone internal gibbus stenosis and deformity can cause compression

Healed disease - Usually internal gibbus and acute kyphotic deformity can also give late onset paraplegia Usually there is a continuous traction compression leading to paraplegia

Compressive Agents are inflammatory edema granulation abscess casseous material sequestra and rarely ischaemic lesion

GROUP B -Late onset- Usually after 2 years of onset of the disease ndash due to recurrence or by mechanical pressure This can be better divided into

paraplegia with active disease and with healed disease

Active disease - Caseous material debris sequestrated disc or bone internal gibbus stenosis and deformity can cause compression

Healed disease - Usually internal gibbus and acute kyphotic deformity can also give late onset paraplegia Usually there is a continuous traction compression leading to paraplegia

MRI bull MRI is the criterion standard for evaluating disk

space infection and osteomyelitis of the spine bull MRI findings useful to differentiate tuberculous

spondylitis from pyogenic spondylitis include thin and smooth enhancement of the abscess wall and well-defined paraspinal abnormal signal

whereas thick and irregular enhancement of abscess wall and ill-defined paraspinal abnormal signal are suggestive of pyogenic spondylitis

bull contrast-enhanced MRI appears to be important in the differentiation of these two types of spondylitis

bull most effective for demonstrating neural compression

GROUP B -Late onset- Usually after 2 years of onset of the disease ndash due to recurrence or by mechanical pressure This can be better divided into

paraplegia with active disease and with healed disease

Active disease - Caseous material debris sequestrated disc or bone internal gibbus stenosis and deformity can cause compression

Healed disease - Usually internal gibbus and acute kyphotic deformity can also give late onset paraplegia Usually there is a continuous traction compression leading to paraplegia
