[X-ray criteria for newly detected infiltrative pulmonary tuberculosis]

The data of examination of 334 patients with infiltrative pulmonary tuberculosis were analyzed. Five types of X-ray signs of the disease were identified. These included: 1) irregularly shaped foci formed by the fusion of foci (31.5%); 2) shadow areas without focal structure (35.6%); 3) round or oval foci (26.3%); 4) wide-walled annular ghosts (3.9%); 5) periscissurites (2.7%). A decay phase was detected in 51.8%. In addition to the size and pattern of an infiltrate, specific foci of lymphohematogenous origin play a great role in the spread of the infiltrate. A diversity of X-ray signs of infiltrative pulmonary tuberculosis makes the verification of its diagnosis difficult.
