A left ICA aneurysm in case 1 (A) is embolized by using multiple coils (B). Postprocedural DWI shows abnormal low-intensity spots with a hyperintense halo (white arrow) in the left parietal (C) and frontal (D) lobes. These are different from a bright spot in the left parietal lobe (E), indicating thromboembolism. These abnormal spots are low intensity on T1WI (F) and T2WI (G) and show a blooming effect on T2*-weighted images (H). Follow-up MR imaging obtained 13 months after the procedure shows that all the abnormal signal spots remain without any signal changes (I–L).

An anterior communicating artery aneurysm in case 5 (A) is embolized by using multiple coils (B). Postprocedural DWI shows an abnormal low-intensity spot with a hyperintense halo (white arrow) in the right frontal lobe (C), which is undetectable on the postprocedural CT (D). Follow-up MR imaging obtained 3 years after the procedure shows that the lesion remains without any signal changes (E and F).
