We present the case of an anomalous origin of the left anterior cerebral artery (ACA) from the supraclinoid segment of the right internal carotid artery. Because of improved imaging quality, anomalies of the ACA-anterior communicating artery (AComA) complex are increasingly recognized on transaxial images. Although most of these anomalies are incidental findings of little clinical significance, some ACA-AComA complex anomalies are clinically significant. Recognition of these anomalies may be instrumental in developing a differential diagnosis or for improved surgical planning.
我们报告一例左大脑前动脉（ACA）起源于右颈内动脉鞍上段的异常病例。由于成像质量的提高，在横轴位图像上越来越多地识别出ACA-前交通动脉（AComA）复合体的异常。尽管这些异常大多是临床意义不大的偶然发现，但一些ACA-AComA复合体异常具有临床意义。识别这些异常可能有助于进行鉴别诊断或改进手术规划。
