Unilateral gunshot wound of the pons: clinical, electrophysiologic, and neuroradiologic correlates
Abstract:
Following a gunshot wound to the face, a 17-year-old male patient experienced a right trigeminal and abducens paralysis, dysarthria, right-sided ataxia, left-sided weakness of the lower part of the face and limbs, and left-sided sensory loss from his neck down. Brainstem auditory evoked potentials showed a decreased P5/P1 amplitude ratio for left ear presentation, and inconsistent replication of P2 and P3 on the right and, to a lesser extent, on left ear click presentations. A computerized tomography scan showed right pontine atrophy. These findings point to a unilateral lesion of the right pons.
