Bilateral identical duplications of the middle cerebral artery are extremely rare. We report this anatomical variation in a 56-year-old woman. The anatomical variation was identified using magnetic resonance angiography, which was performed to evaluate cerebrovascular disease. Bilaterally, one middle cerebral artery originated from the internal carotid artery bifurcation and the other originated from the internal carotid artery terminal segment. The anatomical variations were incidental findings, and the patient was asymptomatic.
大脑中动脉双侧完全重复极为罕见。我们报告了一名56岁女性的这种解剖变异情况。该解剖变异通过磁共振血管造影得以识别，此次造影是为评估脑血管疾病而进行的。双侧的大脑中动脉，一支起源于颈内动脉分叉处，另一支起源于颈内动脉终末段。这些解剖变异为偶然发现，该患者并无症状。
