Asymptomatic Dysplasia Epiphysealis Hemimelica of the Shoulder in a Skeletally Mature Patient with Normal Function

Figure 4

MR images of the left shoulder revealed the inferomedial mass projecting toward the inferior capsular recess, with sharpening of the articular cartilage of the humeral head, but no signs of OA. Cartilaginous components of the tumor showed intermediate T1-weigthed signal and hyperintense proton density- (PD-) weighted signal. In contrast, bone marrow of the tumor showed hyperintense T1-weighted signal and intermediate-to-low PD-weighted signal.
