  • Look Inside

We have recently encountered a rare case of anterior cerebral artery dissecting aneurysm, presenting cerebral infarction and subarachnoid hemorrhage, associated with fibromuscular dysplasia (FMD). A 50- year-old woman was admitted to our hospital with complaints of headache and hemiparesis. A right caro- tid angiogram obtained 9 hours after the onset revealed stenosis and slight dilatation in the A1 portion of the anterior cerebral artery. At 12 hours after the onset, the patient fell into a coma. CT scan showed dif- fuse subarachnoid hemorrhage. An angiogram hadrevealed aneurysmal dilatation and double lumen intheA1 portion, but, 34 days after the onset, angiogramshowed growth of the aneurysm in the Al portion andstenosis in the A2 and A3 portions. At 38 days afterthe onset, the trapping of the dilated aneurysm topre-vent rerupture was performed. Pathological diagnosiswas concluded to be FMD. We concluded that FMDcaused stenosis as well as the formation and ruptureof the dissecting aneurysm in the anterior cerebralartery.
