Abstract:
Objective To investigate the CT features of active pulmonary tuberculosis.Methods The clinical data and HRCT in 79 patients with histologically proved active pulmonary tuberculosis were studied retrospectively.The diagnosis of active pulmonary tuberculosis was based on positive acid-fast bacilli in sputum (43 patients) and the features at the serial radiographs obtained treatment period(36 patients).Results The main CT finding of active pulmonary tuberculosis were centrilobular nodules in 65 cases(82.3),tree in bud appearance in 65 cases(82.3),thickening of bronchial wall in 58 cases(73.5), consolidation in 61 cases(77.3), cavity in 56(73.2), fluid-bronchogran in 53cases(72.8),ground-grass sign in 45 cases(56.8),line shadows in 55 cases(73.1),pleural thickening in 21 cases (26.6), hilar and mediastinal adenopathy in 12 cases(15.1) and more two abnormal findings co-existed in 79 cases.The centrilobular nodules (n=25) ,tree in bud appearance (n=26) ,thickening of bronchial wall(n=8), consolidation (n=19) and ground-grass shadows (n=21) were improved after therapy .Conclusion The active pulmonary tuberculosis are of some specific HRCT manifestations,which may be helpful to improve the dignosis combined with other clinical formation.
