Abstract

A rare abnormality of the A₁ segment of the anterior cerebral artery (ACA) is reported. The right ACA bifurcated into two parts at the middle point of the A₁ segment, and these segments did not rejoin. The superior right A₁ segment connected with the left A₁ and formed a single pericallosal artery. The inferior right A₁, from which the right ophthalmic artery originated, had no connection with the left A₁.
