1. The bones are diffusely osteopenic and have a “chalky” appearance
The bones are diffusely osteopenic and have a “chalky” appearance. The distal right clavicle is partially resorbed. There are extensive vascular calcifications in the arm. There is a large expansile lytic lesion in the distal humeral shaft through which there is a nondisplaced pathologic fracture. A second lytic lesion is present within the glenoid. Although the differential diagnosis for lytic osseous lesions is broad and includes entities such as metastatic disease and multiple myeloma, in this patient with features of renal osteodystrophy, the best diagnosis is Brown tumors. Indeed, these were proven to be Brown tumors of hyperparathyroidism.
