Accessory middle cerebral artery associated with two intracranial aneurysms
Objective and importance: albeit very likely underdisclosed, duplication of the middle cerebral artery (MCA) is a rather unfrequently recognized angiographic finding. In this instance the anomaly was associated with two intracranial aneurysms, one ruptured. Clinical presentation: an anomalous, twin-like MCA, departing from a dominant left pre-communicating anterior cerebral artery and extending...
متن کاملFenestrations of the middle cerebral artery associated with aneurysms.
A present. Computed tomography (CT) demostrated an intracerebral hematoma in the right temporal lobe, and right carotid angiography showed an aneurysm arising from the bifurcation of the right MCA and a fenestration at the origin of the same MCA (fig. 1). At surgery marked arteriosclerosis in the vicinity of the aneurysm was found . The aneurysm was clipped at its neck. The fenestrated artery a...
متن کاملAccessory middle cerebral artery originating from callosomarginal artery.
An accessory middle cerebral artery (AMCA) is a variation of the cranial vascular system. It usually originates from the anterior cerebral artery, particularly from its proximal part and supplies the orbitofrontal and prefrontal regions of the territory of the middle cerebral artery (MCA). It is reported in approximately 3% of dissections (Teal et al., 1973; Yasargil, 1984; Umansky et al., 1988...
متن کاملAneurysm at the origin of the accessory middle cerebral artery.
An aneurysm at the junction of the accessory middle cerebral artery and the horizontal portion of the anterior cerebral artery is reported. The importance of this anomalous artery is discussed with regard to the genesis of aneurysms of the anterior cerebral artery.
متن کاملDistal anterior cerebral artery mirror aneurysms and middle cerebral artery aneurysms.
A 52-year-old woman presented with bilateral distal anterior cerebral artery (ACA) mirror aneurysms, in addition to two right middle cerebral artery (MCA) aneurysms. The left distal ACA and right MCA aneurysms were clipped through right interhemispheric and right pterional craniotomies. The right distal ACA aneurysm was thrombosed. Distal ACA aneurysms tend to be multiple, but mirror aneurysms ...
