case_images: A computed tomography (CT) head demonstrated a 4 cm x 6 cm hyperdensity and edema with mass effect on left frontal area (Figure 1).
case_images: (A) Sagittal CT head angiography demonstrates A2 aneurysm (arrow). Diagnostic subtraction angiography (B) and (C) exhibit complete occlusion of A2 aneurysm after primary coiling (arrows).. Abbreviation: CT, computed tomography.

case_images: A CT angiography of the head demonstrated a pericallosal cerebral aneurysm (Figure 2A). An anterosuperiorly projecting azygous A2 aneurysm, measuring 4.5 mm x 5.5 mm with a neck width at 3.5 mm and a small daughter sac, was completely obliterated with primary coiling (Figure 2B and C).
case_images: (A) Axial MR T1 with contrast demonstrates heterogeneously enhancing lesion along midline and left frontal area (arrow). (B) Axial MR FLAIR demonstrates perilesional edema (arrow).. Abbreviations: MR T1, T1-weighted image magnetic resonance; MR FLAIR, magnetic resonance-fluid-attenuated inversion recovery.
