case_images: Brain imaging showing bilateral aneurysms.(A) T1-weighted axial brain magnetic resonance (MR) scan showing large bilateral cavernous carotid aneurysms (CCAs), with a larger multilobulated aneurysmal sac on the right; (B) Brain computed tomography (CT) angiography showing large bilateral CAAs measuring approximately 21 x 17 x 16 mm on the right and 18 x 15 x 16 mm on the left; (C,D) MR and CT angiography confirming the presence of large bilateral CAAs, unchanged in size from previous scans.

case_images: Axial T1 and T2 weighted images and MRA demonstrated large bilateral CCAs, with a larger multilobulated aneurysmal sac on the right, along with fetal origin of posterior cerebral arteries and small basilar artery (Figure 1A). A CT angiography of brain vessels confirmed the presence of bilateral large CCAs, measuring approximately 21 x 17 x 16 mm on the right and 18 x 15 x 16 mm on the left (Figure 1B). MR and CT angiographies performed 4 months later showed no change in the bilateral CCAs compared to previous scans (Figures 1C,D).
