[Ultrasonic diagnosis of liver hydatidosis].

The paper is concerned with a study of an ultrasound picture of verified hydatidosis in 62 patients. The symptoms of hydatid cysts are the presence of daughter cysts and "hydatid sand", cuticular membrane desquamation, local cyst wall thickening and parietal layers, a necrotic zone in a preparasitic space and cyst calcification. The detection of these symptoms helps to estimate not only the type of a hydatid cyst but also the state and character of parasite activity permitting a choice of therapeutic tactics.
