Bottom Line: An infraoptic course of the anterior cerebral artery is exceedingly rare.Robison first described this anomaly from an anatomic dissection in 1959.A unilateral anomalous infraoptic anterior cerebral artery is more common than anomalies of bilateral infraoptic anterior cerebral arteries.

ABSTRACT
Variations of the anterior cerebral artery-anterior communicating artery complex are commonly identified in aneurysm surgery. An infraoptic course of the anterior cerebral artery is exceedingly rare. Robison first described this anomaly from an anatomic dissection in 1959. A unilateral anomalous infraoptic anterior cerebral artery is more common than anomalies of bilateral infraoptic anterior cerebral arteries. We present the case of an unruptured aneurysm at the anterior communicating artery in a patient with bilateral infraoptic anterior cerebral arteries, identified by computed tomography angiography and verified during surgery. Implications for aneurysm formation and surgical treatment are discussed.

Figure 1: Preoperative computed tomography angiogram demonstrates the ACoA aneurysm (A) and low bifurcation of the internal carotid artery (B, C). Reconstructed images show the aneurysm, which projects posteriorly (D).

Mentions: Our patient developed symptoms of episodic left arm twitching. His family history included significant intracranial aneurysms. Imaging demonstrated a 5-mm ACoA aneurysm which projected posteriorly with early bifurcations of the ICA bilaterally (Fig. 1, Fig. 2). The A1 segments were identified as they traversed the pituitary fossa in an unusually low and laterally directed course, indicating their infraoptic nature.
