[Ultrasonic examination in diagnosis of hydatid echinococcosis].

Out of 247 patients operated for suspected echinococcosis of the liver, 21 (8.5%) cases of non-parasitic diseases of the liver and other organs were revealed: non-parasitic cysts (7), hemangioma (4), abscesses (4), malignant tumors (3), hydronephrosis of the right kidney (2), polycystosis of the liver and right kidney (1). Analysis of echotomographic picture of cystic structures showed that combinations of symptoms did not correspond to echinococcus cyst. Interpretation of echotomographic symptoms in diagnosis of hydatid echinococcosis may lead to diagnostic mistake if location, size, form of cyst, pattern of complications and phase of vital activity of parasite were not taken into account. Results of ultrasound investigation (USI) is more important than data of serologic studies. It is necessary to perform poly-positioned USI for prevention of diagnostic mistakes.
