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).
(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.
