[Radiodiagnosis of echinococcosis of the lungs].

The paper is devoted to analysis of radio-diagnostic findings of 79 patients with parietal round pulmonary formations. All the patients were investigated by x-ray and ultrasound, perfusion scintigraphy of the lungs with a postural test was performed in 43 of them. Diagnostic x-ray and echographic methods were compared and evaluated in terms of defining the origin of pulmonary formations. The origin of pulmonary formations was established by x-ray in 50 of 79 patients (63.3 per cent) whereas ultrasound findings proved correct in 74 of 79 patients (93.6 per cent). Perfusion scintigraphy can be recommended to patients with pulmonary echinococcosis only for limited indications when a necessity arises to assess the lesser circulatory state in terms of patients' functional operability.
