A 36-year-old female patient was admitted to our hospital with a rare case of aneurysm at the origin of the accessory middle cerebral artery (MCA) manifesting as severe headache and vomiting. Neurological examination did not detect any abnormalities or consciousness disturbance. Computed tomography demonstrated diffuse subarachnoid hemorrhage. Magnetic resonance angiography showed an aneurysm in the horizontal portion of the left anterior cerebral artery (A 1 ). Digital subtraction angiography and three-dimensional digital subtraction angiography demonstrated a saccular aneurysm originating at the junction of the left A 1 and accessory MCA. Another accessory MCA originated at the proximal portion of the left A 2 without an aneurysm. Two accessory MCAs were found on the left. Neck clipping was performed via a left pterional approach. One month after admission, she was discharged without neurological deficits.

“…3) One case presented with visual disturbance and a large aneurysm was found compressing the right optic nerve. 14) The formation and growth mechanisms of aneurysm at the junction of A 1 and accessory MCA have not yet been clarified. No contributory family history or past history was identified in any of the 11 cases.…”

“…14) The current total is only 10 reports, including our own, of patients with an aneurysm of the accessory MCA (Table 1). [2][3][4][5]8,[10][11][12]14) Eight of these patients, including our own, had a saccular aneurysm arising at the junction of the accessory MCA and the A 1 segment. 2,4,5,8,10,12,14) The direction of these aneurysms was inferomedial in four cases and supramedial in four cases.…”

“…His concepts have been widely accepted by other authors. [2][3][4][5][8][9][10][11][12]14,15) The incidence of the accessory MCA is 0.3% to 2.7% in autopsy series. 1,7) The angiographic incidence of accessory MCA is 0.32%.…”

A 30-year-old man presented with a rare ruptured saccular aneurysm located at the junction of the accessory middle cerebral artery and the horizontal portion (A 1 segment) of the anterior cerebral artery. A right frontotemporal craniotomy was performed and the aneurysm was clipped through a transsylvian approach. The postoperative course was uneventful and he was discharged in good condition. The transsylvian approach is the method of choice for such aneurysm.
