• Fig B 37-1 Osteosarcoma. Coronal T1-weighted image shows extensive soft-tissue involvement of this large mass involving the proximal femur.46

• Fig B 37-2 Chondrosarcoma. Axial T2-weighted image of the chest demonstrates non-homogeneity of the rib lesion. Areas of low signal intensity represent calcified portions of the mass.45

• Fig B 37-3 Ewing's sarcoma. (A) Coronal and (B) sagittal T1-weighted images demonstrate the intraosseous and extraosseous extent of this tumor of the distal femur.45

• Fig B 37-4 Malignant fibrous histiocytoma. Coronal T1-weighted image shows the large humeral lesion with soft-tissue extension.46

• Fig B 37-5 Plasmacytoma. Axial contrast T1-weighted, fat-saturated image demonstrates an enhancing mass that arises from the left iliac bone and produces extensive bone destruction and a large soft-tissue mass. (Courtesy of Jim Wu, MD, Boston)

• Fig B 37-6 Lymphoma. Axial T1-weighted image shows diffuse marrow changes and a large associated soft-tissue mass.46

Fig B 37-7 Paget's sarcoma. Coronal T1-weighted image demonstrates both the bone destruction and the large soft-tissue mass.46

• Fig B 37-8 Metastasis. Sagittal T2-weighted STIR image shows a mass arising in the sacrum that has a large soft-tissue component and causes extensive bone destruction. (Courtesy of Jim Wu, MD, Boston)
