SUMMARY: We present the case of a patient with a fusiform aneurysm of the M1 segment of the middle cerebral artery (MCA) in which endovascular stent placement without coiling was performed. A 3.5-mm x 25-mm LEO self-expanding stent was deployed along the fusiform aneurysm of the horizontal MCA M1 segment. Digital subtraction angiography showed progressive thrombosis at 6 months and complete thrombosis of the fusiform MCA aneurysm at 12 months.
