Abstract
We report metatarsal metastasis in SPECT/CT in a 65-year-old man, 5 years after radical right nephrectomy. Tumor from first metatarsal was histopathologically proven from clear cell renal cell carcinoma. Metatarsal metastasis is very rare. Less than 0.01% of patients have metastases in the foot bone. Tumor histotype is mainly lung cancer. Metastases from renal carcinoma are often lytic with a poor osteoblastic response, there may be limited uptake of the 99mTc-MDP tracer, and all uncertain regions should be diagnosed with SPECT/CT, if it is possible.
