[Perioperative radiodiagnosis in children and adolescents with pulmonary tuberculosis]

Routine X-ray examination indicated that the rate of cavernous and fibrocavernous tuberculosis was 21.4 and 25.9%, respectively. Computed tomography (CT) showed that the ratio of patients with cavernous tuberculosis to those with fibrocavernous one changed and was equal to 14.3 and 33.0%, respectively. The number of patients diagnosed as having fibrocavernous tuberculosis increased. According to the traditional studies, the number of patients with one lobe being affected turned out to be higher. Accordingly, that of patients with involvement of the whole lung or two lungs proved to be underestimated at cavitary analogue X-ray study (AXS) or linear tomography (LT). Preoperative X-ray CT detected a larger number of caverns and tuberculomas. While identifying decay cavities in tuberculomas, X-ray CT enhanced the effectiveness of a study from 17 to 36% as compared with the results obtained at AXS and LT that revealed specific changes in the intrathoracic lymph nodes and inoculation foci in the lung. The nature and scope of elective operations were reconsidered from the results of X-ray CT.
