VIVA CASES

Page 2: Viva segment 1

CASE ONE

New born with bilious

vomiting

Page 3: Viva segment 1

CASE ONE

What are the findings ?Supine radiograph of the abdomen of an infant shows two prominent gas distended viscus in the upper abdomen c/w dilated stomach and

duodenum. Lack of bowel gas in distal bowel

What is your diagnosis? Duodenal atresia – Double bubble sign with lack of distal bowel gas is diagnostic

What are the differentials ? With a dilated stomach and duodenum and some gas in distal bowel, D/D include stenosis,Ladd’s bands,annular pancreas, duodenal web, malrotation, preduodenal portal vein, duplication cyst

Page 4: Viva segment 1

CASE ONE

What are the associations of duodenal atresia ?

Seen in 50-60% - Down’s, CHD, vertebral &rib anomalies, GI anomalies

What are associated findings on an infantogram ?

Eleven pairs of ribs & altered iliac index (Down’s); rib & vertebral anomalies, L- R shunt

( always look for features of Down’s in a pt with double bubble )

CASE TWO – H/O progressive head enlargement

Page 6: Viva segment 1

CASE TWO

What are the salient findings ?

Lateral skull radiograph of a child :

- flocculent calcification in the sellar & suprasellar region with sellar enlargement,

- enlarged cranium & sutural diastasis

- pneumoventricle ( post pneumoencephalography)

What is the diagnosis ?

How would you confirm your diagnosis ?

Craniopharnygioma – sellar and suprasellar calcification in a child suggests the diagnosis

MRI Brain / CECT head f/b HPE

Page 7: Viva segment 1

CASE TWO

What would you expect to see on CT/ MRI ?

CT - Mixed solid cystic suprasellar mass with calcifications and obstructive hydrocephalus.

MRI – MC hyperintense, MB iso/hypo on T1; hyper on T2, solid components may enhance

CASE THREE

Q. What are the findings of X ray ?Reduction in L5 height, tear drop fracture antero-inferior

body

Page 9: Viva segment 1

CASE THREE

Page 10: Viva segment 1

CASE THREEQ. Do you get any additional information on MRI ?

Two column fracture of L5 . No canal compromise

Q. Would any additional investigations be needed to assess this injury?

Lateral skiagrams of lumbar spine in flexion and extension for assessment of stability +/ - DEXA Hip and spine

CASE FOUR - 45 days old infant with microcephaly and seizure

Page 12: Viva segment 1

CASE FOUR

NCCT Head:

• Bilateral basal ganglionic and periventricular calcification

• Hourglass configuration of brain with pachygyria

What are the findings ?

Congenital CMV infectionWhat is the diagnosis ?

Page 13: Viva segment 1

CASE FOUR What are the differentials ?

1. Causes of bilateral ganglionic calcification

2. Causes of normal intracranial calcification

1. Congenital toxoplasmosis – calcification more haphazard

2. Chronic lymphocystic choriomeningitis – macrocephaly commoner than microcephaly. May be indistinguishable

CASE FIVE - Chronic smoker with Haemoptysis

Page 15: Viva segment 1

CASE FIVEWhat are the findings?

1. Multiple thin wall cysts of varying sizes b/l , relative sparing of lower zones.

2. Non-cavitating centrilobular nodules in right zone. 3. Prominent Main pulmonary artery 4. Bronchial artery tortuous - Chronic lung disease with plexogenic arteriopathy

What are the differentials?Differential For Against
