Axial T2-weighted magnetic resonance imaging (MRI) scans demonstrating mass like lesion, suggesting a partially-thrombosed large aneurysm which has mass effect at the perisylvian area (asterisks) (First low, left). Right internal carotid artery (ICA) angiography revealing a fusiform aneurysm in proximal middle cerebral artery (arrow) (First low, center). Axial T2-weighted MRI scan revealing an increased right proximal MCA fusiform aneurysm with hemosiderin deposit, mixed hematoma suggesting multiple hemorrhagic events (asterisk) (First low, right). Cerebral (Second low, left) and reconstructed CT (Second low, center) angiography demonstrating a multilobulated fusiform aneurysm of the proximal MCA region (arrow in Second low, left; arrowhead in center). Cerebral angiography showing that a stent-assisted coil has been well positioned at the right proximal MCA fusiform aneurysm (asterisks) (Second low, right; Third low, left). Follow-up right ICA angiography demonstrating complete occlusion of the fusiform aneurysm (asterisks) with blood flow preservation in the distal MCA (arrowhead in H) (Third low, center; right).
