 We describe the case of subarachnoid hemorrhage and cerebral infarction that developed simultaneously and was caused by suspected dissection of the anterior communicating artery. A 65-year-old woman presented with sudden onset of headache and nausea. Head computed tomography(CT)and magnetic resonance imaging revealed subarachnoid hemorrhage in the interhemispheric fissure and a spotty ischemic lesion in the right frontal cortex. Both, CT angiography and angiography with arterial catheterization showed an aneurysmal dilatation of the anterior communicating artery. A repeated CT angiography nine days later demonstrated enlargement of the aneurysmal dilatation. The patient underwent craniotomy under general anesthesia. Under the microscope, a thick hematoma was seen infero-dorsally from the anterior communicating artery. Two fenestrations of the anterior communicating artery were identified. After removal of the hematoma, a fusiform dilatation of the anterior communicating artery with a firm and reddish wall was confirmed. The lesion was coated with a teflon sponge and fibrin glue. The patient's postoperative course was uneventful. A follow-up CT angiography two months after surgery revealed shrinkage of the lesion, when compared with preoperative images.
