He most frequently registered change of pulmonary parenchyma at IPA were nidi and foci of hyperchromogeneity (5-6 points at Fleindler’s scale) of pulmonary tissue – 75%.

Alveolar infiltration was detected in 1/3 of patients approximately.

One of the most serious complications of IPA is infarction pneumonia-pneumonia; it was registered by Bioplasm 9d nls analyzer-graphy in 7 (13%) patients. At the same time we detected areas of hyperchromogeneity of pulmonary tissue of conical form, adjoining pleura with broad side. With the same frequency hydrothorax development was revealed.

It should be notes that revealed nidi, foci and pulmonary tissue infiltration areas in majority of cases had subpleural location.
