摘要

A 62聽year-old male with prostate cancer, recently complaining lumbar pain with elevated PSA level (6.83聽ng/ml) was referred for evaluating bone metastases. Bone scintigraphy with ^99mTc-MDP demonstrated intense uptake on third lumbar vertebra. Postoperative biopsy of the lesion on third lumbar vertebra revealed adenocarcinoma metastasis. For evaluating distant metastases and restaging, ¹⁸F-FDG PET-CT was performed postoperatively. On PET-CT imaging there were cervical and left parailiac lymph nodes with FDG uptake, destruction on third lumbar vertebra level and intense soft tissue mass FDG uptake on the same area. Additionally, FDG uptake was detected on right iliac crest. On the CT images obtained by integrated PET-CT scanner, this uptake was matching with lytic bone metastases. The superiority of ¹⁸F-FDG PET-CT for demonstrating osteolytic bone metastases compared to bone scintigraphy was presented in a case of prostate cancer in a patient with bone and lymph node metastases.
