Intraparenchymal haematoma related to true middle meningeal artery aneurysm: a case report

Abstract

Non-traumatic middle meningeal artery aneurysm and rupture resulting in intracranial haemorrhage is rare. In the present case, a 73-year-old man was admitted to hospital with a history of a minor head trauma. A CT scan of the head revealed a 2×2 cm intraparenchymal haematoma without significant mass effect in the left temporal lobe. The cerebral angiogram revealed a middle meningeal artery aneurysm. Intracerebral haematoma due to extracranial aneurysm is extremely rare, but should be considered when the history is suspicious and cranial CT is non-contributory.

“…Twenty-seven cases of nontraumatic MMA aneurysms have been reported to date. 1,2,[5][6][7][12][13][14][15][16][17][18][19][20]22,[24][25][26][27][28][29][30]34,35,37,38 They may present with intracranial hemorrhage or may be discovered incidentally. Many MMA aneurysms have occurred in association with high-flow states, such as Paget's disease, 5,24 dural arteriovenous fistulas and arteriovenous malformations, 2,13,14,27,29 moyamoya disease, 7,16,28 and meningiomas.…”
