During the period from March, 1980 to February, 1981 in the Department of Raiology, Jeonbug National University Hospital, we reviewed the raidiologic findings of 879 cases diagnosed pulmonary tuberculosis and 56 cases diagnosed tuberculous pleural effusion without lung parenchymal lesion on initial chest P-A film in adult(older than 16 years). The results were as follows. 1. Sex distribution of pulmonary tuberculosis was 668 cases(76%) in male, 211 cases (24%) in female, the average age 44.6, and the highest incidence in the third and sixth decade with similarity. 2. The incidence of pulmonary tuberculosis was highest in the springtime (29.5%) and its peak particularly in May. 3. Classifying the extent of pulmonary tuberculosis into minimal, moderately advanced and far advanced pulmonary tuberculosis, their ratio was 6 :1 , 5 : 1 with the concrete data of 553 cases (70.8%), 136 cases(17.4%), and 92 cases (11.8%) respectively. 4. In the cases of minimal pumonary tuberculosis t e location of TB -lesion incidence were right upper, left upper and both upper lobes in the ratio of 45 :27 : 28(%). 5. The radiological findigs of pulmonary tuberculosis appeared various, but the ill-defined patchy density of exudative reaction signifying an initial lesion were the most 935%). 6. As an unusual type of tuberculosis, cavitary TB was 38 cases(4.3%), among them, in 3 cases (7.9%) there appeared air-fluid level. Miliary TB was 8 cases (0.9%) , mostly abundant inthe youngsters (esp. in the third decade), and female immensely outnumbered male. Tuberculoma was 10 cases 91.4%), female precede male in the ratio of 7 ; 3 m and in right upper lobe the incidence was highest (50%). 7. Without lung parencymal lesions, the cases to have caused an tuberculous pleural effusion was 56 (6.0%), and in the years of 16 to 29 it was the most frequently with 26 cases(46.4%). 8. With complicated pulmonary tuberculosis, 78 cases (9.5%) showed to combine with other diseases. Among them pleura effusion was 14 cases (1.7%) , and pneumothorax 14 cases 91.7%) which were the most frequent. 9. Spread of tuberculosis beyond the lung to other organ was 28 cases ( 3.1%) and frequent in female. characteristically. Among them, bone and joint TB was 16 cases and the most abundant in number, inparteicular , spine TB was the most frequent with 10 cases(36%).
