Head CTA showed a 4 mm aneurysm involving the M1 segment of the left middle cerebral artery (MCA) and no acute hemorrhage (Figure 1).
PMC3349957_02
Computed tomography angiography showing a 5 mm aneurysm arising from the anterior communicating artery. The aneurysm had not been detected until 3D reconstruction was performed.
