Rupturing Anterior Communicating Artery Aneurysm during Computed Tomography Angiography: Three-Dimensional
1Department of Neurosurgery, Dongsan Medical Center, Keimyung University School of Medicine, Daegu, Korea.
Abstract:
Computed tomography angiography (CTA) is commonly used in setting of subarachnoid hemorrhage, but imaging features of aneurysm rupturing taking place at the time of scanning has rarely been described. The author reports a case of actively rebleeding aneurysm of the anterior communicating artery with intraventricular extravasation on the hyperacute CTA imaging. The rebleeding route, not into the third ventricle but into the lateral ventricles, can be visualized by real-time three-dimensional CT pictures. The hemorrhage broke the septum pellucidum and the lamina rostralis rather than the lamina terminalis.
