“…[1][2][3][5][6][7][8][9][10] Only one case occurred at the proximal MCA in a male patient involved in a motor vehicle accident, who was admitted in a drowsy state with delayed hemorrhage. 4) The MCA may have been damaged by the sphenoid ridge, but no evidence of the aneurysm's histological features was reported.…”

A 72-year-old male presented with a post-traumatic false aneurysm of the right proximal M 2 artery with massive subarachnoid hemorrhage after closed head injury. Serial computed tomography (CT) and angiography showed the development of the aneurysm which was verified at autopsy. He was admitted in a drowsy state just after a motorcycle accident. Initial brain CT showed subarachnoid hemorrhage without skull fracture. Follow-up brain CT showed a huge hematoma in the right temporal lobe. He died 47 hours after the accident. Histological examination of the aneurysm showed a false aneurysm. Delayed diagnosis of traumatic aneurysms leads to high mortality, so early surgical treatment is essential to save such patients.

“…Serial follow-up CT or angiography also showed the aneurysm had decreased in size in several cases. 1,8,10) Prevention of bleeding from the tear of the false aneurysm is important for a good prognosis. However, patients with severe neurological deficits at the onset or after delayed hemorrhage may be difficult to save.…”

A 76-year-old man presented with a traumatic aneurysm of the left internal carotid artery which caused repeated subarachnoid hemorrhages within 20 hours of a fall from a height. Early computed tomography (CT) detected no brain abnormalities, but repeat CT found subarachnoid hemorrhage. Internal carotid angiography detected a pseudoaneurysm, which was not treated because of his poor clinical condition. He died of multiple organ failure. Early detection of a traumatic intracranial aneurysm is important for the prevention of aneurysmal rupture, or``delayed'' apoplexy. Review of 171 cases with traumatic aneurysms from the literature found that false negative angiography occurred only in three cases on post-trauma day 7 and thereafter. Early diagnostic angiography within a week of the initial trauma is indicated if traumatic aneurysm is suspected to detect early signs of irregularity, spasm, and narrowing of the arterial wall. Repeat angiography is indicated if aneurysmal formation is still highly suspected in spite of negative initial angiography.
