A 57-year-old man was admitted with SAH caused by the ruptured aneurysm of the anterior communicating artery. This saccular aneurysm was successfully treated by coil embolization. On day 6, he had the difficulty of verbal communication, however, he could talk in writing. ABR was normal and the diffusion-weighted image of MRI showed no ischemic change. SPECT revealed hypo-perfusion in both temporal lobes including the auditory cortex. Therefore, we diagnosed that this symptom was caused by cerebral vasospasm. After treatment of cerebral vasospasm, the patient's hearing difficulty improved and SPECT showed the recovery of cerebral perfusion. We experienced a rare case of cortical deafness caused by cerebral vasospasm of bilateral auditory cortex. In this case, the hypoperfusion of the auditory cortex was determined by SPECT. We report here the first case that cerebral blood flow of cortical deafness during vasospasm of SAH was evaluated by SPECT.
