Case 1. The ventral surface of the osteochondroma (A) is covered by the cartilaginous cap. The macroscopic aspect of the dorsal surface of the tumor (B) reveals the bony stalk (star). In the computed tomography (CT) scan, the lesion can easily be identified on the ventral aspect of the right scapula (C; arrowheads). Its localization on the margo superior close to the angulus superior is demonstrated by a three-dimensional reconstruction of the CT images (D; arrow).
