Abstract

Abstract:

Objective: To investigate the CT features in patients with inactive pulmonary tuberculosis and active pulmonary tuberculosis. Methods: All of 181 patients with inactive pulmonary tuberculosis (inactive group) and 166 patients with active pulmonary tuberculosis (active group) diagnosed and treated in Chongqing Public Health Medical Center from August 2020 to July 2021 were retrospectively collected, and CT manifestations in the two groups were analyzed. Results: The percentages of lesions involving one lobe (19.9% (36/181)) and two lobes (25.4% (46/181)) in the inactive group were significantly higher than that in the active group (10.8% (18/166) and 13.3% (22/166), respectively)(χ²=5.392 and 8.128 respectively, and P=0.020 and 0.004, respectively). The percentage of lesions involving 5 lobes (21.5% (39/181)) was significantly lower than that in the active group (48.2% (80/166))(χ ²=27.283, P=0.000). The percentages of lesions in the right middle lobe and lower lobe as well as the left lower lobe (38.7% (70/181), 45.3% (82/181) and 46.4% (84/181), respectively) were also significantly lower than those in the active group (69.9% (116/166), 77.1% (128/166) and 68.7% (114/166))(χ ²=33.903, 36.657, 17.520; Ps=0.000). CT findings: the incidences of patchy consolidation (22.1%, 40/181), caseous lesions (0.6%, 1/181), cavity (16.6%, 30/181), pleural effusion (0.6%, 1/181), lymphadenopathy (18.8%, 34/181) and tree-in-bud signs (18.2%, 33/181) in the inactive group were significantly lower than those in the active group (80.1% (133/166), 7.2% (12/166), 27.1% (45/166), 31.9% (53/166), 53.6% (89/166), 66.9% (111/166))(χ ²=116.598, 10.703, 5.671, 64.868, 45.906 and 84.365, respectively, and P=0.000, 0.001, 0.017, 0.000, 0.000, 0.000, respectively). The incidences of bronchiectasis (61.3%, 111/181), parenchyma cavity (12.2%, 22/181), pleural calcification (10.5%, 19/181), calcified nodules (34.8%, 63/181), sclerosis (37.0%, 67/181) and fibrosclerosis (91.7%, 166/181) in the inactive group were significantly higher than those in the active group (44.0% (73/166), 4.2% (7/166), 3.6% (6/166), 16.9% (28/166), 0.6% (1/166), 27.7% (46/166))(χ ²=10.464, 7.124, 6.135, 14.403, 70.576 and 149.222 respectively, and P=0.001, 0.008, 0.013, 0.000, 0.000 and 0.000, respectively). Conclusion: The lesions of inactive pulmonary tuberculosis in the lower lobe are less distributed, and fibrosclerosis, bronchiectasis, sclerosis, calcified nodules and pleural calcification are more common signs on CT. CT scanning plays an important role in assessing the activity of pulmonary tuberculosis.
