• It is usually caused by LMN pathology, commonly disruption of conduction from the common peroneal nerve (L4-L5)
• L4-L5 radiculopathy is the next most common recognized cause of foot drop, usually caused by herniated nucleus pulposus or foraminal stenosis

Central or UMN causes of Foot Drop
• Central or UMN causes are extremely rare but must be considered
• Compression of these fibers along the path from the cortex, internal capsule , the cerebral peduncles, and the ventral spinal cord, can potentially result in disruption of signal to the lumbar nerve roots
![Page 106: Introduction Department of Neurology CPC](https://reader036.fdocuments.us/reader036/viewer/2022070515/587c112d1a28ab03768b69af/html5/thumbnails/106.jpg)

Myelopathy & foot drop The UMNs of the leg are
organized somatotopically from the medial motor cortex down the internal capsule to the ventral gray matter of the spinal cord, where they are grouped in longitudinally oriented columns

Spinal dAVF• They comprise 3%–16% of all
compressive spinal cord lesions
• Attributed to 30% of idiopathic myelopathies.
• They are most often diagnosed on imaging by a neuroradiologist
• They can present with symptoms of myelopathy and radiculopathy mimicking a plethora of pathologies.

• Reported a case of a 79-year-old female who presented with back pain and a left foot drop. MRI suggested edema in the conus medullaris
• Spinal angiogram revealed serpiginous enhancement from T11-L1 consistent with a type I AVM (Dural AV fistula)
• She eventually underwent successful embolization with complete occlusion of the Spinal AVF

TAKE HOME MESSAGE
• Although rare and underappreciated, Central causes of foot drop must be included in the workup once peripheral causes have been ruled out
• A thorough history and physical examination may reveal signs of UMN disease, including hyperreflexia, and Babinski response
• Neurophysiology studies should be included in the workup and can assist in ruling out peripheral causes
• Most central causes of foot drop(identified on imaging) can have rather dramatic recovery following resection or decompression
