A 57-year-old patient with recurrent Acom aneurysm. Initial angiogram showed a ruptured Acom aneurysm; maximal height 4.5 mm, neck size 3.1 mm (a). Immediate post-embolization image (b) showed neck remnant occlusion without sac filling (class II). After one year, cerebral angiography (c) revealed a recurrence of aneurysm. Stent-assisted coiling (arrowhead) was successfully performed, but neck remnant was still observed (d and e). After one year after retreatment, MRA revealed a more recurrence of aneurysm neck. Acom = anterior communicating artery; MRA = magnetic resonance angiography
