[Bladder tumor presenting multiple osteoblastic bone metastases].
A 67-year-old man who had undergone partial cystectomy for a bladder tumor (stage pTlb) about two years earlier, was seen with the complaint of lumbago. KUB examination revealed multiple osteoblastic lesions at the lumbar vertebrae and pelvic bone. Furthermore, additional osteoblastic lesions were detected at the thoracic vertebrae, ribs, humeral bones, femoral bones and claviculae. Osteolytic lesions also were recognized at the ribs and claviculae, although osteoblastic change was dominant. Pathologically, transitional cell carcinoma had invaded the bones, and it was suspected that they had metastasized from the bladder tumor.
