Abstract：Objective: To study the CT features of primary pulmonary chondroma for improving diagnostic accuracy. Methods: The clinical data of eight patients with primary pulmonary chondroma proved by pathology of surgical specimens or biopsy were analyzed retrospectively. All patients had CT plain scanning, including 6 cases of enhanced scanning. Results: All of the 8 lesions were solitary. Six lesions were in the right lung and 2 in the left lung. CT findings: All lesions were solitary nodule or mass with well defined boundary, without cavity and satellites; 3 lesions had slightly lobular borderl; 5 lesions showed inner or periphery punctate and patchy calcifications, 3 lesions without evident calcifications; in 6 cases of enhanced scanning, 4 lesions had no evident enhancement and 2 lesions demonstrated moderate heterogeneous enhancement. Conclusions: Primary pulmonary chondroma is a rare benign tumor of lung, its CT findings have some characteristics, and should be differentiated from tuberculoma, harmatoma and peripheral lung cancer.
