View the question. Findings/Diagnosis The AP radiograph of the left hip (see Figure 1) shows periarticular, well-defined erosions of the left hip (white arrow) without joint space narrowing or osteophytes. There is no fracture. There are surgical clips and a calcified mass in the right hemipelvis (black ellipsis), representing a failed renal transplant. The coronal STIR…

View the question. Findings/Diagnosis The AP radiograph of the left shoulder (see Figure 1) shows erosions of the proximal humeral and glenoid articular surfaces (black arrows) without joint-space narrowing. There is a well-defined marginal erosion with overhanging edge at the junction of the proximal humeral articular surface and rotator cuff insertion on the greater tuberosity (ellipse)….
View the question. Findings/Diagnosis The radiographs demonstrate diffuse sheetlike and tumefactive calcifications throughout the subcutaneous tissues, muscle and fascia of the pelvis and right hand. The underlying bones and joint spaces appear normal. The differential diagnosis for soft tissue calcification is extensive and includes metabolic disturbances (particularly of calcium and phosphate), trauma (e.g., injection sites,…
