Hydatid Cyst of the Uterus

[摘要] Background:Hydatidosis is a common zoonosis that affects a large number of humans and animals, especially inpoorly developed countries. The infesting parasite has four forms namedEchinococcus granulosis,E. multilocularis,E. vogeliandE. oligarthrus(very rare in humans). The most frequently involved organs are liver followed by the lung.The involvement of the genital tract is rare and the occurrence in the uterus is an extreme rarity.We report a case ofhydatid cyst in the uterus.Case:A 70-year-old female with a history of hydatid cysts of the liver, was admitted to hospital after complaining oflow abdominal pains.On physical and gynecological examinations, no pathological finding was detected. However,the uteruswas significantly large for a postmenopausal patient. Transvaginal sonography (TS) revealed a cystic massin the uterus with a size of 7× 6 cm. After further examinations a subtotal hysterectomy was performed. Microscopicexamination showed scolices ofEchinococcus granulosis.Conclusion:Hydatid cysts in the genital tract are rare and the occurrence in the uterus is an extreme rarity.Differentiationbetween hydatid cyst and malignant disease of the related organ is difficult. To avoid misdiagnosis, a carefulexamination of pelvic masses should be carried out in endemic areas for detection of hydatid cysts.
