The cellular change of the pulmonary tuberculous lesions may be devided into two groups, exudative and prolirerative form by their course and fate. In the most cases, the patients usually have very much complex type of cellular changes. Therefore, the shadows of the chest films in pulmonary tuberculosis are also much variable in nature. And Daniel 1) said that knowledge of the pathology of tuberculosis and an appreciation of the method of progression and healing are essential to proper interpretation of the films.
Author, having reviewed 33 cases of resected tuberculous lung obtained in N. M. T. H. for one year from Oct. ´75 to Sep.´76 by surgical managements, classified the Pathological fin-dings such as; 1) casseation only, 2) tuberculoma, 3) atelectatic lung 4) cavitary lesion and 5) atelectasis with cavity, and examined the relationship between the roentgenolical characteristics of the chest films and the pathological process of tuberculous lesions of the resected lungs.
The result were obtained as follows.
(1) Tuberculoma was commonly appeared in S_(1) segment in right and S_(2) segmentin left.
(2) Atelectasis and destroyed lung were more commonly appeared in left lung than right, and their containing rate of cavity was 82%
(3) Cavities were mostly appeared in S_(1) and S_(2) segments of both lung and the appearance-rate of cavity on S_(6), segment was higher in left than right. And among the cavitary lesions of the resected lung, cavity was not seen in the preoperative chest films in 22%
(4) The configuration, thickness and sharpness of the walls of cavities, which revealed the cavitary shadows in the preoperative chest films, were mostly depended on the degree of increased collagenous fiber of the wall, existance of perifocalitis, and more orless of the caseous masses on the inner surface of the cavity wall.
