Multiple myeloma is a cancer which is characterized by proliferation of malignant B-cells and plasma cell infiltration of bone marrow. Lytic lesions are one of its hallmarks, on radiological assessment. We report 2 cases who presented within 1 year to our hospital with bony lytic lesions on CT scan. They were investigated for multiple myeloma; however, there were no further features to suggest this. Both patients were confirmed to have prostate cancer. This is unusual as prostate cancer produces sclerotic lesions (unusual hardening or thickening of the bone).
