Renal cell carcinoma metastasis

Discussion:

A common site of metastasis of renal cell carcinoma is the skeleton, giving rise to lytic expansile metastases.

On occasion the first presentation ( presenting symptoms ) may be from a bony metastasis.  In this case the lesion was thought to initially represent a primary bone lesion, which is within the differential.

Solitary bone lesions may be broadly divided into agressive and non-aggressive from their appearances on plain film.
