Figure 2.

CT angiography three-dimensional surface-rendered reconstructions in axial (A), coronal oblique (B), and sagittal (C) planes show the large right supraclinoid internal carotid artery ruptured aneurysm (long white arrow) and smaller adjacent posterior cerebral artery (PCA)-P1 segment aneurysms oriented superiorly (short white arrow) and inferomedial (dotted white arrow). The right PCA-P1 and P2 segments are shown by the green arrows and a right dysplastic posterior communicating artery is identified by the red arrows.
