Abstract Objective: To analyze the imaging appearance and to explore the diagnostic value of CT in primary malignant tumors of the ribs. Methods: Twenty-six cases with primary malignant costal tumors proved by operation and pathology were analyzed, and radiographic features were analyzed retrospectively. Results: There were 14 cases of chondrosarcoma with 78.5% arising at the costochondral junction, characterized by irregular and lytic bone destruction with cartilage matrix calcification inside. After intravenous injection, no obvious enhancement was seen. There were 4 cases of plasmacytoma, characterized by solitary or multiple, punched-out or eroded lesions. Osteosarcoma(three cases) appeared as osteolytic or mixed bone destruction, irregular calcific densities were found in one case. Ewing’s sarcoma(two cases) demonstrated as ill-defined, osteolytic lesions with a large soft tissue mass in one case. The rest were one of each of the following: non-Hodgkin’s lymphoma, chordroma, fibrosarcoma, and liposarcoma. Conclusion: The primary malignant tumors of the ribs are a complicated group and rarely encountered, some of which demonstrate the classic radiological features, but some cases with nonspecific radiological features, and the final diagnosis should consider about clinical, imaging and pathology.
