Early Diagnosis with Electrodiagnostic Study and Successful Treatment of Foot Drop Caused by Intraneural Ganglion cyst

다국어 초록 (Multilingual Abstract)

Foot drop is a commonly encountered symptom in electrodiagnostic lab. It is uncommon for peroneal nerve to be compressed by ganglion cyst around the fibular head, but it is important to differentiate peroneal lesion from lumbar radiculopathy which occurs more often. With treatment followed by prompt and exact diagnosis, we can minimize motor weakness due to nerve damage. We report a case in which a 60-year-old woman who complained of right foot drop was diagnosed with peroneal nerve palsy caused by intraneural ganglion cyst around the fibular head.
In comparison with other case reports about peroneal nerve palsy caused by ganglion cyst, the diagnosis of this case was made immediately after onset of the foot drop by electromyogram and the patient recovered from motor weakness after surgery.
