  • a One aneurysm was identified in the infarct hemisphere (unruptured anterior falx artery aneurysm), and 8 aneurysms were identified in the hemorrhage hemispheres, consisting of 5 ruptured aneurysms (1 at the splenial artery, 2 at the anterior choroidal artery, 1 at the lenticulostriate artery, and 1 at the posterior cerebral artery) and 3 unruptured aneurysms (2 at the basilar apex and 1 at the superior cerebellar artery).
