We present a female in her forties with hypertension and tobacco use who had an enlarging right MCA bifurcation aneurysm. Angiography showed a large aneurysm with the superior M2 arising near the neck and the inferior M2 from the dome, precluding clip reconstruction or endovascular therapy. She underwent right pterional craniotomy with STA–MCA bypass to the inferior M2 followed by aneurysm clipping. Postoperative angiography confirmed complete exclusion and patent bypass. She was discharged neurologically intact.
