Figure 6. A plain radiograph of a 47-year-old woman who presented with a painful swelling in the lower rib cage on the left side suggested malignancy. CT shows irregular rib expansion and destruction with a break in continuity of the posterior aspect of the sixth and seventh ribs. Fine nodular opacities (<1 mm in diameter) are disseminated throughout the lung fields. CT repeated 10 months later showed dramatic resolution of the lesion, though residual bone deformity with a minimal pleural reaction was found to persist.
