Digital cerebral angiography showed aneurysms located at the posterior communicating artery (PCom) bilaterally, supraclinoid left carotid lateral wall (LWC), and at anterior communicating artery (AComA) [Figure 1].

The LCW was nicely coiled; with respect to the left PCom, there was intraaneurismal contrast retention even in the venous phase of the angiography along with modification of the aneurismal sac format [Figures 2 and 3], which indicated the possibility of pseudoaneurysm formed due to previous intrawall break because there was a previous angiogram showing the same saccular aneurysm without dissection signals.
