Objective To classificate the CT manifestations of the pulmonary tuberculosis cavitations and its pathology, evaluate its diagnosis and differential diagnosis. Methods Seventy-six cases of tuberculosis cavitations were proved by pathology and clinic. They are divided into two types according to the morphology of cavitations: infiltration cavitation and fibrosis. All patients had CT imaging, and analyzed by three of the radiologists, disagreement among them was discussed and a consensus reached. Results CT manifestations of tuberculosis cavitations are as follow: 51 cases of infiltrative cavitations and 25 cases of fibrosis. After treatment most infiltrative cavitations turn better and fibrosis had no change obviously. The imaging of cavitations had correlation with its pathology. Conclusion CT classification is valuable for diagnosis and differential diagnosis of tuberculosis cavitations, and also useful in evaluation activity and prognosis.
