Accessory middle cerebral artery associated with an accessory anterior cerebral artery.
Purpose: Although both accessory middle cerebral artery (MCA) and accessory anterior cerebral artery (ACA) are not rare anatomical variations, their combination is rare and there are only a limited number of reports of such combinations.
Methods: We report a case of accessory MCA associated with an accessory ACA diagnosed by magnetic resonance angiography (MRA).
Results: A 39-year-old woman visited our hospital because of right facial discomfort. She underwent 1.5-Tesla magnetic resonance imaging and MRA. MRA showed a left accessory MCA originating from the left ACA A1 segment. MRA also showed an accessory ACA that formed a triplicated ACA at its A2 segment.
Conclusion: Careful imaging assessment is important to identify multiple anatomical variations such as an accessory MCA associated with an accessory ACA. In our case, this rare anatomical variation was confirmed by 1.5-Tesla MRA.
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.
