Abstract

The cerebral arterial circle exhibits considerable morphological variability. Variations in the middle cerebral artery (MCA) are infrequent occurrences that can be readily identified via imaging techniques. The current imaging report describes a rare variant of the MCA consisting of a duplicate origin, which was incidentally discovered in a 42-year-old female patient through computed tomography angiography. The duplicated origin of the MCA was identified on the left side of the cerebral arterial circle, forming an arterial ring with the temporopolar branch of the MCA originating from one of its limbs. The remainder of the arterial circle demonstrated no variants. It is essential to distinguish variants of the MCA without conflating them. The present variant is accurately characterized as a 'duplicate origin", it should not be confused with fenestrations, and has a reported prevalence of 0.1%. Comprehending such arterial variations is vital prior to undertaking endovascular or neurosurgical procedures in the region.

大脑中动脉的重复起源：一种罕见的变异。

脑动脉圈表现出相当大的形态变异性。大脑中动脉（MCA）的变异是不常见的，可以很容易地通过成像技术识别。目前的影像学报告描述了一种罕见的由重复起源组成的MCA变异，偶然发现于一位42岁的女性患者，通过计算机断层血管造影。在脑动脉圈的左侧发现了MCA的重复起源，形成了一个动脉环，MCA的颞极分支起源于它的一个肢体。其余的动脉圈没有变异。区分MCA的变体而不将它们混为一谈是很重要的。目前的变异被准确地描述为“重复起源”，它不应与开窗混淆，据报道患病率为0.1%。在该地区进行血管内或神经外科手术之前，了解这种动脉变异是至关重要的。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
