Neurologic, audiologic, and electrophysiologic sequelae of bilateral temporal lobe lesions
K. J. Ho, P. Kileny, D. Paccioretti and D. R. McLean
A 67-year-old woman with demonstrated intact peripheral and brain-stem
auditory pathways presented with sudden deafness secondary to sequential
bilateral temporal lobe infarcts. Initial examination revealed no
behavioral response to sounds and a mild Wernicke's aphasia. Hearing
gradually returned but auditory agnosia persists. Changes seen on the
computed tomographic scan and the middle latency auditory evoked response
over a seven-month period were analyzed and suggest that the peak component
of the middle latency response arises from Heschl's gyrus.
