      Highlights

      • To our knowledge, this is the first case report to describe an infundibulum at the origin of an accessory MCA.
      • It is important to differentiate infundibula from aneurysms as the work-up and management differs.
      • Infundibula typically do not require surgical intervention or follow-up imaging.

      Abstract

      We present a case of an infundibular dilation at the origin of an accessory middle cerebral artery emanating from the distal A1 segment of the anterior cerebral artery. There was also partial vessel wall enhancement along this infundibulum. To our knowledge, this is the first case report with such findings.
