66 year-old male history of RCC with bone metastases. Study is obtained to evaluate for osseous metastatic disease and is thus limited for evaluation of solid organs.Large exophytic left inferior pole cystic renal mass with significant soft tissue components measuring 7.7 x 6.7 cm. Subcentimeter right inferior pole renal mass which demonstrates low T1/T2 signal, but is too small to accurately characterize. Small right inferior pole renal cyst. There is diffusely abnormal bone marrow signal intensity and diffusion restriction within the axial skeleton and bilateral proximal femurs and humeri compatible with metastatic disease.
Large left renal mass compatible with RCC with increasing diffuse bone metastases within the axial skeleton as well as smaller metastatic deposits within the proximal femurs and humeri.
