Background and Importance: Anatomical variations are widely described in the anterior communicating artery (AComA) complex of the circle of Willis. Some variants may be associated with increased risk of aneurysm formation and rupture and impose a challenge for surgical interventions in treating aneurysm.

Context 1
... 74-year-old female patient presented to the emergency department at our tertiary care referral center in Shiraz, Iran with the symptoms of sudden severe headache, and loss of consciousness. The Glasgow Coma Scale was at 13 at presentation (Hunt & Hess grade 3 III) with mild bilateral temporal horn prominence without intraventricular hemorrhage (Fig. 1A). The patient provided informed consent for the diagnostic investigations and therapeutic procedures and for the use of the clinical information and images for research purposes or for reporting in peerreviewed journals. The patient had a medical history of hypertension and dyslipidemia which was chronically managed by Captopril, ...
Context 2
... multiplanar brain CT angiography with three-dimensional reconstruction showed a duplicate AcomA with a saccular aneurysm (neck diameter 5.7 mm; dome height 9 mm) projecting superioposteriorly from the distal AcomA branch accompanied by an anomalous artery arising from the anterior surface of that same AComA (Fig. 1B). The anomalous artery was determined to be an accessory or triplicate ACA. The dome-to-neck ratio was ...
