Selective Coil Embolization of Ruptured Fusiform Aneurysm Involving Anterior Choroidal Artery and Posterior Communicating Artery

•A ruptured fusiform aneurysm of the dICA involving the AchoA and PcomA was treated with selective coil embolization.•An 86-year-old woman was admitted with subarachnoid hemorrhage.•CT and CT angiography showed diffuse subarachnoid hemorrhage with a fusiform aneurysm.•Cerebral angiogram showed a fusiform aneurysm in the supraclinoid segment of the ICA with a daughter sac.•The suspected bleeding point was selectively obliterated using the double-microcatheter technique.
