Diffuse osteoblastic metastases in prostate cancer

The bone scan and T2 weighted midsagittal image of the thoracic spine is from a 50-year-old male with known prostate carcinoma. The bone scan (A) shows extensive osteoblastic metastases involving almost all the visualized bones, including the entire spine, pubic symphysis, and probably sternum. The MRI (B) shows diffuse heterogeneity and a compression of T11 (arrow). The findings are consistent with extensive blastic metastasis from primary prostate carcinoma.
