[Echinococcosis in pregnancy].

Hydatid disease affects sheep and cattle and is caused by the larval form of Echinococcus granulosus. Affected human beings are only chance intermediate hosts. We present a woman admitted in her 22nd week of pregnancy because of upper abdominal pain and persistent vomiting. The presumptive diagnosis of hydatid cyst of the liver was established by ultrasound, X-ray and CT examinations. At laparotomy a 10 x 7 cm hydatid cyst was removed from the liver. She recovered completely and delivered spontaneously at term. There was no evidence of hydatid disease in the newborn or in the placenta.
