Abstract: Objective To explore the CT and pathologic manifestations of the pulmonary chondroma,to improve the diagnostic accuracy and reduce the misdiagnosis.Methods The CT data of 6 patients with pulmonary chondroma proved by pathology were analyzed retrospectively.Results All 6 cases were solitary,3 cases occurred in the right lung and the other 3 cases occurred in the left lung.The diameter of the lesions ranged from 1.0 cm to 5.1 cm.2 cases showed lobulated shape,4 cases showed round shape.4 cases showed circumscribed margin,2 cases showed blurrmed margin.Furthermore,calcification was detected in 1 case.Conclusion Pulmonary chondroma has some characteristic CT features,including vascular border sign and begonia sign.However,it should be differentiated from pulmonary hamartoma,peripheral lung cancer and sclerosing pneumocytoma.
