Figure 1

Conventional osteosarcoma. Elderly male presenting with a history of lower back pain diagnosed as conventional osteogenic sarcoma following biopsy. Anteroposterior (AP) radiograph (a) and axial CT scan (b) of the pelvis reveal aggressive bone-forming neoplasm involving the left ilium (asterisk). Follow-up axial T2 fat-saturated image (c) after tumor resection demonstrates an osseous metastasis with a characteristic peripheral halo (Arrow), which should not be confused with a metallic susceptibility artifact.
