Imaging findings
The radiograph shows a subtle lower chest wall lesion with fluffy, arc-like calcification and enlargement and deformity of the adjacent rib. CT shows a calcified chest wall mass that expands and destroys the rib, pushes through the diaphragm, and has an ill-defined margin with the liver, consistent with invasion. Coronal images show a clear margin against the liver in one area and blurred infiltration in another. The medial part of the tumor has less calcified matrix and bulges out as a separate lobule, which raises concern for a more aggressive, possibly dedifferentiated component.
Key takeaways
A calcified chest wall mass with rib expansion and destruction is typical of chondrosarcoma. Check carefully for spread through the diaphragm into the liver, because it changes the surgery. This tumor needed diaphragm resection and reconstruction. A part of the tumor with less matrix and faster growth may represent a higher-grade or dedifferentiated component.
