Abstract
We describe a variant where the A2 segment of one anterior cerebral artery anastomose distal to the origin
of the anterior communicating artery with the A2 segment of the contralateral anterior cerebral artery. The
anastomoses are seen without any hypoplasia or aplasia of A2 segments prior to anastomoses unlike azy‐
gous or bihemispheric anterior cerebral artery. The anastomoses occur prior to bifurcation of the anterior
cerebral artery into pericallosal and callosomarginal arteries.
