Synovial Lipomatosis of the Glenohumeral Joint

Figure 2

MRI of the right shoulder. (a) Axial proton density fat suppressed weighted image showing regions of low signal intensity within the joint effusion. (b) Sagittal proton density fat suppressed weighted image showing suppression of the signal intensity of the lesions, similar to subcutaneous fat. Bone erosion is present at the superior aspect of humeral head representing a Hill-Sachs fracture. (c) Sagittal T1-weighted image showing a large joint effusion and heterogeneous signal intensity within the periphery of the joint, suggestive of synovial hyperplasia.
