case_images: Head CT demonstrated left SDH including the interhemispheric fissure (Fig. 1). 3D-CTA performed at the referring hospital revealed  5-mm saccular aneurysms at the left ICA and right basilar-superior cerebellar artery junctions, along with left A3-A4, and right A2-A3 aneurysms (Fig. 2).
case_images: Lateral view (left to right) of three dimensional CT angiography taken at our clinic, showing cerebral aneurysm in the ACA of right A2A3 (white arrow) and left A3A4 (white arrow head).
