Abstract

Purpose: Although both accessory middle cerebral artery (MCA) of distal origin and anterior communicating artery (ACoA) duplication are not rare anatomical variations, their combination is extremely rare and there are only a few reports of such combinations.

Methods: We report a case of distal origin accessory MCA associated with ACoA duplication diagnosed by magnetic resonance angiography (MRA).

Results: A 63-year-old man visited another hospital for screening examinations for cerebrovascular disease. He was noted to have a possible intracranial aneurysm at the A1-A2 junction of the right anterior cerebral artery on MRA. He was referred to our hospital for its management. More detailed 3-Tesla MRA volume rendering images revealed ACoA duplication, not an aneurysm. MRA also showed the right distal origin accessory MCA arising from the A2 segment distal to the ACoA duplication.

Conclusion: This rare combination of anatomical variations requires careful imaging assessment. MRA volume rendering images were useful in our case.

远端起源的副大脑中动脉与模仿动脉瘤的前交通动脉重叠有关。

目的：虽然远端起源点附属大脑中动脉（MCA）和前交通动脉（ACoA）重复都是不罕见的解剖变异，但它们的组合极为罕见，仅有少数报道。方法：我们报告一例经磁共振血管造影（MRA）诊断的远端起始副MCA合并ACoA重复。结果：男性，63岁，到其他医院进行脑血管疾病筛查。在MRA上发现右大脑前动脉A1-A2交界处可能有颅内动脉瘤。他被转介到我们医院接受治疗。更详细的3-Tesla MRA体积渲染图像显示ACoA重复，而不是动脉瘤。MRA还显示右远端起始副MCA起源于ACoA重复的远端A2段。结论：这种罕见的解剖变异组合需要仔细的影像学评估。在我们的案例中，MRA体渲染图像很有用。

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.
