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 ...
متن کاملAn Unruptured Anterior Communicating Artery Aneurysm with Bilateral Infraoptic Anterior Cerebral Arteries. Case Report and Review of the Literature
Variations of the anterior cerebral artery-anterior communicating artery complex are commonly identified in aneurysm surgery. An infraoptic course of the anterior cerebral artery is exceedingly rare. Robison first described this anomaly from an anatomic dissection in 1959. A unilateral anomalous infraoptic anterior cerebral artery is more common than anomalies of bilateral infraoptic anterior c...
متن کاملMicrosurgical anatomy of the anterior cerebral artery – anterior communicating artery complex: An Indian study
Objective: The microsurgical anatomy of the anterior cerebral artery (ACA), anterior communicating artery (ACoA), distal anterior cerebral artery (DACA) and its branches is complex and is known for its frequent variations. The purpose of this study was to document the microsurgical anatomy of this region in Indian population. Methods: Ten anterior cerebral artery complexes from cadaveric brain ...
متن کاملA Rare Embryologic Variation: Anterior Communicating Artery Aneurysm Associated with Carotid—Anterior Cerebral Artery Anastomosis or Infraoptic Course of the Anterior Cerebral Artery
Aneurysms of the complex of the anterior cerebral artery are frequently associated with anatomic variations of the circle of Willis. We describe a case of aneurysmal rupture of the anterior communicating artery, a variant of the anterior cerebral artery. The aneurysm appeared to be situated on this vessel proximal to the infered site of the AcoA. Surgery was performed at the 6th day after hemor...
متن کاملA misleading distal anterior cerebral artery aneurysm
BACKGROUND Aneurysmal rupture causing pure acute subdural hematoma (aSDH) is rare. In the four previously reported cases of distal anterior cerebral artery (ACA) aneurysm resulting in pure aSDH, blood distribution in the interhemispheric (IH) space has systematically incriminated the distal ACA as the source of rupture. We present a misleading case of a distal ACA rupture resulting in convexity...
