We report a rare case of a large thrombosed aneurysm at the peripheral artery of the middle cerebral artery presenting subarachnoidal hemorrhage after the Ramsay Hunt syndrome. A 64-year-old male who had suffered from Ramsay Hunt syndrome suddenly presented consciousness disturbance and the left hemiparesis on April 12, 2001. CT showed a subarachnoid hemorrhage mainly in the right sylvian fissure. MRI showed a low intensity mass on T2-WI. His right carotid angiogram revealed a dilatation of the parietal artery with a retention of the contrast material. Surgery was performed on April 13. Aneurysm with the large thrombus had neck at the dilatic lesion in the parietal artery. Neck clipping and coating at the dilated parietal artery was performed. The postoperative course was good, but he developed left hemiparesis again on April 22. On April 23, CT showed infarction in the right middle cerebral artery territory. Right carotid angiogram revealed an occlusion of the parietal artery and segmental stenosis of the angular artery.
