We report about a patient with a solitary tibial metastasis of a prostatic carcinoma. Metastases to the peripheral skeleton are relatively rare with a frequency of only 1-2% and are mainly found in cases of general spread of the disease. Complaints due to peripheral solitary metastases often cause misinterpretations. Bone scintigraphy is the primary method in the diagnosis of skeletal metastases, and is sometimes supported by specific radiographs. MRI yields excellent images of the extension of the tumor. It is therefore of high diagnostic value in the preoperative definition of the metastatic spread in bone and neighbouring soft tissue structures.
