The azygos anterior cerebral artery (ACA) is a rare variation in the circle of Willis. Azygos ACAs often associated with other vascular or nonvascular anomalies. These aneurysms can be noninvasively imaged either by conventional computed tomography (CT) angiography or magnetic resonance angiography, but digital subtraction angiography is the gold standard for diagnosis. We report a case of saccular aneurysm of azygos ACA, diagnosed by multidetector CT cerebral angiography and treated by craniotomy and clipping of aneurysm. The clinical significance of the rare anomaly is highlighted. We report this rare clinical experience with review of the literature.
