Foot drop caused by a brain tumor: a case report.

Foot drop is commonly caused by lumbar radiculopathy, peroneal nerve injury, spinal stenosis and other systemic diseases. It is usually thought as peripheral etiology, but it could be attributed to a central lesion, too. However, central lesions are rarely reported. We report a case diagnosed as a left parasagittal parietal tumor, in which drop foot was the only abnormal neurologic finding.
