[Difficulties in the diagnosis of chronic toxoplasmosis with lung involvement]

A case of chronic acquired toxoplasmosis combined with lung impairment is described. The diagnosis was made on the basis of the data obtained as a result of the use of the latest clinical and instrumental research methods and a specific serologic test. The diagnosis was verified morphologically on thin sections of the sputum. The authors provide data on the diagnostic search for approaches to the differentiation between parasitic diseases resulting in dissemination to the lungs with calcification of the foci and broncholithiasis, tuberculosis.
