Abstract
Skeletal muscle is a very rare location for the metastasis of renal cell carcinoma. We report a 48-year-old man with multiple metastases in skeletal muscles 4 years after right radical nephrectomy was carried out for grade III renal cell carcinoma. The tumors located in the right psoas, paravertebral, and gluteus medius muscles. We performed magnetic resonance imaging for detection metastatic lesions in our patient. In this case report, we discuss the characteristics of these metastatic lesions on magnetic resonance imaging.
