Foot drop due to cranial gunshot wound.
OBJECTIVE
We present a case of foot drop from hemorrhagic contusion after cranial gunshot, which has never been reported.


METHODS
A 21-year-old man was admitted with inability of dorsiflexion 1 day after a tangential gunshot wound of the scalp. The scalp skin was cut by the rifle bullet. He had foot drop and his neurological examination was normal except for weakness at dorsiflexion of the right foot. Pathological reflexes and sensation failure were not detected. T1- and T2-weighted magnetic resonance images showed hyperintense contusion at the right superior frontal gyrus and mild subdural hemorrhage. Peripheral nervous system examination was electrophysiologically normal. Motor-evoked potentials showed the location of the lesion at the motor cortex because no electrical record was obtained from the right anterior tibial and extensor digitorum brevis muscles, and there was a normal record on the left. Six months later, the patient's neurological examination was uneventful.


CONCLUSIONS
When a cranial gunshot wound injury victim presents with foot drop, the central causes should be included in the differential diagnosis list.
