Small basilar artery fenestration mimicking an aneurysm.
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.
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.
