Summary

Perianeurysmal vasogenic oedema is a recognised although rare phenomenon following endovascular treatment of certain intracranial aneurysms. We present a unique case of asymptomatic perianeurysmal vasogenic oedema following bare platinum coil embolisation of an incidentally discovered right middle cerebral artery aneurysm that slowly increased over a period of 6 years before stabilising and regressing. During this time, the coiled aneurysm per se remained completely stable on serial magnetic resonance angiography.
