Whileperforming a radiologic examination of multi-detector computerizedtomography images of vascular structures in the right shoulder regionof a 43 years old female Turkish patient who admitted to ourhospital, we observed a complete ossification of the superiortransverse scapular ligament. This case report, which is discussed inthe clinical perspectives of anatomic variations, puts forth that radioanatomicimages about variations, like the one used in this report, areof importance while illuminating the etiopathologic background ofentrapment neuropathies of the shoulder region.
