ABSTRACT=An aneurysm at the origin of the accessory middle cerebral artery (AccMCA) from the A1 segment of the anterior cerebral artery (ACA) as the supplying artery to the twig-like MCA is exceptional. Here, we report such a case and present a review of the literature. A 56-year-old male suffered subarachnoid hemorrhage. Digital subtraction angiography confirmed a twig-like MCA and a ruptured aneurysm at the origin of the AccMCA. Endovascular coil embolization for the aneurysm was performed. After the microcatheter was positioned in the aneurysm, soft coils were delivered to finish complete embolization. Postoperatively, the patient recovered uneventfully. One month later, the patient returned to his job without any neurological deficits. Postoperative CT at the three-month follow-up showed that the brain tissue was normal. By reporting our case and reviewing the literature, we found that endovascular coil embolization for such aneurysms at the AccMCA origin was feasible in selective cases.
