A Case of Lateral Medullary Infarction Combined with Sudden Hearing Loss / 대한뇌혈관학회지

ABSTRACT

We report a 62-year-old female with ischemic disturbance of left inner ear. The patient had a sudden onset episode of vertigo, tinnitus and hearing loss. Neurologic examination revealed incomplete Honor syndrome, left facial sensory impairment and sensorineural hearing loss. Brain MRI showed subacute infarct on medial aspect of left lateral medulla. Ischemic disturbance of inner ear have been reported only in patients with the anterior inferior cerebellar artery syndrome. Therefore, this patient who had only acute ischemic disturbance of inner ear and lateral medulla was considered to be very rare. This phenomenon may be due to variations of anterior inferior cerebellar artery anatomy.
