(a), (b), and (c) illustrate the areas of origin of the recurrent artery of Heubner (black arrow). (a) The RAH originated from the precommunicating part (A1) of the anterior cerebral artery. (b) The RAH originated at the level of the anterior communicating artery (ACoA). (c) The RAH originated from the postcommunicating part (A2) of the anterior cerebral artery. (d) and (e) illustrate the double recurrent artery of Heubner. (d) The double RAH originated from different points. (e) The double RAH originated as one stem, which later bifurcated.
