Figure 3: (a) Digital subtraction angiography (DSA) frontal projection showing right M1 segment aneurysm with perforator arising from the fundus. (b) DSA frontal projection parenchymal phase immediate post procedure revealing stasis of contrast within the aneurysm. (c) Magnetic resonance angiography at 4 weeks - Absent flow signal in aneurysm. (d) DSA frontal projection at 6 months - absent flow in the aneurysm with normal filling of perforators
