Abstract

Fenestration of the basilar artery is a well-known anatomical variant which can be misdiagnosed as arterial dissection. Misdiagnosis as an aneurysm is also possible and has been reported. A 41-year-old woman was referred to our hospital for evaluation of a suspected aneurysm of the proximal basilar artery trunk found on 1.5 T magnetic resonance angiography. More detailed 3 T magnetic resonance angiography revealed a small fenestration, not an aneurysm. The diameters of the vessels in the two limbs forming the fenestration were remarkably different: one limb had almost the same diameter as the main basilar artery, while the other had a very small diameter and coursed in an arc on the right outer side. The smaller limb of the fenestrated segment appeared to mimic an aneurysm on the initial magnetic resonance angiography. Careful imaging assessment is important to identify basilar artery fenestrations, especially small ones and those with a large difference in diameter between the two limbs.

类似动脉瘤的小基底动脉开窗。

基底动脉开窗是一种众所周知的解剖变异，可被误诊为动脉夹层。误诊为动脉瘤也是可能的，也有报道。一位41岁的女性，因在1.5 T磁共振血管造影中发现疑似基底动脉近端动脉瘤而转诊至我院。更详细的3t磁共振血管造影显示一个小开窗，而不是动脉瘤。形成开窗的两条肢体的血管直径明显不同：一条肢体的直径几乎与基底动脉主动脉相同，而另一条的直径非常小，在右外侧呈弧形。开窗段的小肢在最初的磁共振血管造影上看起来像动脉瘤。仔细的影像学评估对于鉴别基底动脉开窗非常重要，尤其是小开窗和两肢之间直径差异较大的开窗。

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.
