title: [Traumatic aneurysm of the peripheral cerebral artery].
abstract: Two cases of traumatic aneurysm of peripheral cerebral artery were reported. Case 1. A 6-year-old girl was severely injured on her head by automobile accident. Plain skull films showed depressed fracture in the left frontal region. Left common carotid angiogram 25 days after the injury revealed small aneurysm of a cortical branch of the anterior cerebral artery. Cranioplasty and removal of the aneurysm was performed. Postoperative course of this patient was uneventful. Case 2. A 4-year-old girl fell downstaris and struck her left temporal region. On admission, she was unconscious and plain skull films showed multiple linear fractures. No aneurysm was demonstrated in the right common carotid angiogram immediately after the head trauma. Since her general condition gradually improved, she discharged 23 days after the head trauma. 63 days after the injury, she developed sudden onset of severe headache, vomiting, and status epilepticus. Right common carotid angiogram showed a large aneurysm arising from a branch of right pericallosal artery at the free edge of the falx. Parent artery of the aneurysm was clipped. Postoperatively, the patient made uneventful recovery. 60 reported cases of traumatic aneurysm of peripheral cerebral artery were reviewed and analyzed in etiology, diagnosis, clinical course, treatment and pathogenesis.
