Prostate cancer: Osteoblastic metastases to the lumbar spine

The patient is a 50-year-old male with metastatic prostate carcinoma. Image (A) is a CT reconstruction of the lumbar spine and shows extensive blastic metastases involving almost all the visualized bones with lytic and compressive changes in T11 (arrow). The T2-weighted MRI (B) shows heterogeneous changes within the bone marrow consistent with metastatic disease. The findings are consistent with extensive metastases from primary prostate carcinoma.
