An unusual variant of the callosomarginal artery from the A1 segment of the anterior cerebral artery.

CONCLUSIONS: Recognizing this variant preoperatively could be helpful in preventing complications of surgery. Careful follow-up studies are necessary in the present case to monitor the development of another aneurysm at the junction between the left CMA and the left A1 segment of the ACA.
