We report a case of a 31-year-old female with multiple intracerebral hemorrhage and subarachnoid hemorrhage. She presented with headache one week before hemorrhage, and a CT scan performed at that time showed no abnormal findings. Neurological examination on admission revealed mild disturbance of consciousness, papilledema, and mild left hemiparesis. CT scans demonstrated intracerebral hemorrhage in the right caudate head and left frontal subcortex, and diffuse subarachnoid hemorrhage. Cerebral angiogram and laboratory examination revealed no abnormal findings. Erythrocyte sedimentation rate, C reactive protein and antiphospholipid antibody were within normal ranges. The patient underwent removal of hematoma by craniotomy. One week after the operation, a subcutaneous hematoma in the area of the craniotomy was found. Cerebral angiography demonstrated an aneurysm of the right superficial temporal artery, which was remote from the craniotomy. This aneurysm was surgically removed and examined. Histopathological examination revealed the presence of a pseudoaneurysm but no inflammation. Although primary angitis of the central nervous system was suspected to be the cause of this disease, a definite diagnosis could not be obtained.
