Magnetic resonance imaging (MRI) showed hyperintensities in the subarachnoid space predominantly in the anterior interhemispheric fissure on fluid attenuation inversion recovery T1 images [Figure 1].
Digital subtraction angiogram of the left internal carotid artery showing the fusiform aneurysm in the proximal pericallosal artery (white arrow in a) and vasospasm in the proximal A1 (black arrows in a). Right ICA angiogram showing severe vasospasm in the left anterior cerebral artery (arrows in b)

Digital subtraction angiogram (DSA) showed fusiform elongated aneurysm with a small bleb in the left distal A2 segment and severe vasospasm in bilateral A1 segments of the ACA [Figure 2].
Left oblique view of left ICA angiogram showing the fusiform aneurysm in A2 (arrow in a). Microcatheter advanced into aneurysm under roadmap guidance and aneurysm packed with coils (arrow in b)

A2 aneurysm. A total of five Axium coils (eV3; Neurovascular) were placed and the aneurysm occluded along with the distal A2 segment [Figure 3].
Post coiling angiogram showing the coil mass (black arrow in a) and proximal stump of A2 (white arrow in a). Capillary phase showing good pial collaterals filling the ACA territory after the coil mass (arrow in b)
