[Usefulness of magnetic resonance imaging for evaluation of therapeutic efficacy of bone metastases from bladder cancer: a case report].

A 70-year-old man had a prostate-invading bladder cancer with multiple bone metastases. The bladder cancer seemed to have metastasized via the vertebral vein system because there was no metastasis in other organs. Transurethral resection of bladder tumor was performed followed by one course of M-VAC (methotrexate, vinblastine, doxorubicin) therapy and MEP (methotrexate, etoposide and cisplatin) therapy. After chemotherapy, magnetic resonance imaging (MRI) of the spine revealed further progression of disease, although bone scintigraphy did not, and the patient died of disease.
