Abstract:

The clinical data/information and CT findings of 75 children with secondary pulmonary tuberculosis, who were diagnosed at Shenyang Tenth People Hospital from August 2012 to September 2017, were retrospectively analyzed. Among 75 cases, their lesions mainly occurred in the posterior or apical segment of the upper lobe of the lung (proportion occurred in the posterior segment of the right upper lobe was 64.0% (48/75), in the posterior or apical segment of the left upper lobe was 62.7% (47/75), in the apical segment of the right upper lobe was 56.0% (42/75)) and the back segment of the lower lobe of the lung (proportion occurred in the back segment of the right lower lobe was 61.3% (46/75), in the back segment of the left lower lobe was 42.7% (32/75)). The lesions in the lungs were in a variety of forms. The most common images of the lesions included fibrous strips (92.0% (69/75)), acinar-like nodules in the lobules & nodular fusion (91.7% (68/75)), patchy shadow (86.7% (65/75)) and light film (80.0% (60/75)); the incidence of tuberculoma was very low (5.3% (4/75)). In the changes of lesion density, the incidence of calcification (58.7% (44/75)) was slightly higher; the most cavities were thick-walled (22.7% (17/75))) or wall-less (10.7% (8/75)). The rate complicated with tuberculous pleurisy (77.3% (58/75)) or bronchial tuberculosis (36.0% (27/75)) was high.
