A 59-year-old Korean female residing in Japan with a history of hypertension presented to the emergency department of our hospital with a sudden headache, hearing loss, and inability to walk. A CT scan showed Fisher group 3 subarachnoid hemorrhage and intracranial hematoma in the left temporal lobe. A CT angiography confirmed an aneurysm located at the bifurcation of the left middle cerebral artery. We performed surgical clipping via a left-sided pterional approach on the day of hospitalization. Neurological examination revealed motor aphasia and sensorineural hearing loss. We performed conservative treatment, and the hearing ability got better. Hearing loss caused by subarachnoid hemorrhage due to ruptured aneurysm of posterior circulation is well known but that caused by anterior circulation has not been reported. Intracranial hypertension or damage of hematoma in the inner ear may be the cause of hearing loss.
