Abstract
Courses and prognosis of the 212 capsulated caseous cavities of tuberculous lesions were observed radiographically.
Rates of the breakdown of the lesions by sex indicated that the male cases had higher rate than the female cases.
By age, the younger ages group showed higher rate than the other ages groups. It seemed that there are some relations between the rate and the patients' rest conditions.
Cavities having sharp tails by x-ray pictures showed high rate of breakdown, especially, in cases of chemotherapy.
Lesions in the left upper lung showed higher rate of breakdown than that of the right upper lung. As for middle part of lung, there was no difference by right and left sides.
In cases of chemotherapy, INH and PAS cases showed higher rate of breakdown of the capsulated caseous lesions than SM and PAS group.
The breakdown of lesions of INH and PAS group started from the central part of the lesions, meanwhile, that of SM and PAS group and non-chemotherapy group started from the peripheral parts of their lesions, generally.
Lesions that showed breakdown picture became almost always to take the course of open cavity.
