case_images: A subsequent brain CT scan, on the 5th SAH day, was negative for SAH but 3D-CT angiogram revealed one large distal fusiform and another 2 smaller aneurysms: one at the right MCA and another at the right PCA (Figures 1 and 2).
case_images: Lateral CTA scans demonstrating an ectatic fusiform dilatation of the involved MCA distal branch with aneurysm. In addition, a saccular smaller aneurysm at the origin of MCA bifurcation and another fusiform smaller aneurysm at the first segment of PCA were demonstrated.

case_images: Furthermore, there was no evidence of any ischemic insult (Figure 7).
case_images: Cerebral angiographic (DSA) image in AP view of right ICA at 6-month follow-up, demonstrating complete obliteration of the embolized aneurysm with retrograde filling of the normal artery distal to the aneurysm. The smaller aneurysm has shown significant reduction in size.
