We report 7 cases presenting with double aneurysms originated from the junction of the internal carotid artery-posterior communicating artery and the ipsilateral internal carotid artery-anterior choroidal artery. It was equivocal in the preoperative angiogram whether 2 adjacent aneurysms were adherent or not. Meticulous dissection of the aneurysms and preservation of blood flow in the parent artery and its branches are required in direct surgery.
