Abstract
|
|
|
|
Foot drop can occur as a manifestation of a number of pathological and clinical conditions and is a fairly common disability encountered in electrodiagnostic clinics. This report describes two cases of atraumatic foot drop. Both cases were electrophysiologically diagnosed as common peroneal neuropathy around the fibular head. Radiographic and surgical findings confirmed intraneural ganglion cyst of common peroneal nerve and the surgical resection was performed. Although the radiographic and surgical findings were compatible with the lesion of common peroneal nerve, the precise analysis of the electrophysiologic findings could differentiate the fascicular involvement in two cases.
