Renal cell carcinoma metastasis


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 aggressive and non-aggressive from their appearances on plain film.
