Monkey’s type of anterior cerebral artery mimicking aneurysm: CT angiography findings
نویسنده
چکیده
Anterior cerebral artery (ACA) is one of the two terminal branches of internal carotid artery that supplies orbitofrontal and medial hemispheric portions of the brain. ACA is topographically and angiograpically divided into a precommunicating (A1) and a postcommunicating (A2, also called as pericallosal artery) parts. An azygos (occurring singly) pericallosal artery in one of the most frequent anomalies of the distal ACA [1]. It can be easily identified when gross examination is made, however even conventional angiographic distinction may sometimes be difficult. An azygos pericallosal artery is also a risk factor for distal anterior cerebral artery aneurysm due to hemodynamic vulnerability [2]. Herein we present a case of azygos pericallosal artery mimicking the anterior communicating artery aneurysm on enhanced cranial computed tomography.

Azygos anterior cerebral artery mimicking an anterior communicating artery aneurysm.
The CT appearance of intracranial aneurysms has been well described. Though a definitive diagnosis often requires angiography, the CT findings are often highly suggestive of these frequent , potentially lethal, and curable vascular lesions. We recently encountered a patient who had the typical CT findings of intracranial aneurysm but whose arteriographic findings showed a large azygos anterior ...

Background: This investigation was conducted in order to study angiographic findings in patients with cerebral aneurysm. Materials and Methods: The study conducted on 136 cases of ruptured cerebral aneurysms between 1995-2000 confirmed by means of 4-vessel cerebral angiography to get an insight to racial, geographic and environmental factors predisposing to the occurrence of subarachnoid hemorr...

Aneurysmal subarachnoid haemorrhage which has a serious mortality and morbitity ratio, occurs approximately 10/100.000 population per year and it is usally caused by rupture of a cerebral artery aneurysm. Aneurysms are classified saccular, fusiform or dissecan by morphological description. Vascular congenital anomalies of the cerebral vessels contribute to saccular aneurysm formation by increas...

The azygos anterior cerebral artery, a rare anomaly in the circle of Willis in which only a single vessel supplies the medial aspects of both anterior cerebral hemispheres, is closely associated with saccular aneurysms. We present three cases of azygos anterior cerebral artery aneurysms among the 781 cerebral aneurysms surgically treated at our institution in an 11-year period. These three case...
