  		Figure 2. 56-year-old female with a chondrosarcoma. Axial CT image demonstrates large tumour arising from the right 6th rib, with "arcs" of central calcification.

  		Figure 3. 62-year-old male with a chondrosarcoma. (a) CT shows the tumour with nodular calcification, arising from the posterior aspect of the left 5th costo-chondral junction. (b) Coronal T2 MRI shows high signal multilobulated anterior chest wall tumour (arrow), with areas of signal void due to calcification.

  		Figure 4. 72-year-old male with chondrosarcoma. Axial CT shows a large mass arising from the anterior left 4th rib, with a marked periosteal reaction.

  		Figure 5. 70-year-old male with a chondrosaroma. (a) Axial T2 MRI shows paraspinal tumour with extensive central signal loss due to matrix calcification, and a high signal tumour margin.

  		Figure 6. 65-year-old female with an osteosarcoma. (a) Chest radiograph shows a large densely calcified mass overlying the left upper chest wall. (b) Axial CT shows a large densely calcified left chest wall mass, situated on the ribs and displacing overlying pectoralis muscles. (c) Coronal T1 MRI shows large chest wall mass with extensive central signal loss (arrow) due to tumour calcification.

  		Figure 7. 30-year-old female with Ewing's sarcoma. Axial CT demonstrates a large soft tissue attenuation mass arising from the left 4th rib, which is irregular and sclerotic.

  		Figure 8. 32-year-old male with Ewing's sarcoma. (a) Axial CT shows large soft tissue tumour (arrow) with well-defined margins. The ribs exhibit a marked periosteal reaction. (b) Axial T2 MRI shows large high signal chest wall mass, with intra-abdominal extension and liver compression.

  		Figure 9. 52-year-old female with multiple myeloma. Axial CT shows a large enhancing soft tissue tumour expanding the sternum, and extending into the anterior and posterior soft tissues. Note compression of the brachiocephalic vein and superior vena cava.

  		Figure 11. 56-year-old male with multiple myeloma. CT image shows marked sternal expansion and deformity, and vertebral destruction with paravertebral soft tissue masses from myeloma.

  		Figure 12. 71-year-old male with right apical adenocarcinoma (Pancoast's tumour). CT shows superior sulcus tumour extending into the ribs and right axilla.

  		Figure 13. 52-year-old female with previous left mastectomy for breast carcinoma (note prosthesis). A large right side chest wall recurrence is seen originating from the sclerotic expanded right 6th rib.

  		Figure 14. 66-year-old male with prior history of lymphoma and bony chest wall recurrence. Extensive soft tissue attenuation tumour arises from the destroyed right 9th rib, and spreads into adjacent soft tissues.
