Abstract

Three-dimensional computed tomographic (3D-CT) angiography is a widespread imaging modality for intracranial vascular lesions. However, 3D-CT angiograms of an anterior communicating artery aneurysm associated with acute retrobulbar optic neuropathy have not been previously described. We present 3D-CT angiograms of an aneurysm of the anterior communicating artery that caused subarachnoid hemorrhage and vision loss in a 39-year old man. The 3D-CT angiograms were consistent with findings identified directly during surgery.

  Fig. 1 Preoperative brain three-dimensional (3D) computed tomographic angiography images. (A) Enhanced axial view shows an aneurysm arising from the junction between the right anterior cerebral artery (ACA) and anterior communicating artery (AComA). (B) Vessel subtractional view shows a large aneurysm in the right ACA at the AComA junction oriented primarily downward. (C) 3D views show the large aneurysm arising from the junction of the right ACA and AComA, oriented primarily downward (blue arrow) toward the right optic nerve (green arrow). (D) Intra-operative view shows the right optic nerve (green arrow), internal carotid artery (blue arrow) and frontal lobe (blue star). After clipping, the ruptured aneurysm with its clip (green star) can be seen arising from the junction between the right ACA and AComA and the pinkish optic nerve (green arrow).
