Renal cell carcinoma is not a frequent malignancy, but its metastases seem to have a predilection for the skeleton. They are invariably osteolytic and therefore hypointense on T1- (Figs. 1-3) and inhomogeneously iso-or hyperintense on T2-weighted images (Figs. 2-4). They are almost always associated with intense pain and often lead to pathologic fractures (Figs. 5-6).
