Primary ovarian hydatid cyst mimicking cyst adenoma: a rare case report

Abstract

Background: Hydatid cysts (HC) are zoonotic diseases that are mainly caused by . Ovarian HC is a rare condition with different and unspecified presentations. Here we report a rare case of primary ovarian HC. Case Presentation: A 47-year-old woman with chronic abdominal pain and left hemipelvic fullness was referred to the Obstetrics Clinic of the Kowsar Hospital of Qazvin. Abdominopelvic sonography revealed a cystic mass, which primarily suggested a cyst adenoma. The tumor marker levels were within normal limits. After surgical resection, histopathological examination showed a cystic mass with dimensions of 10×6×3 cm, smooth external and internal aspects, wall thickness of 0.3 cm, and multiple pieces of irregular gray membranous tissue. The patient was treated with albendazole 3 months after surgery, and a 6-month follow-up sonogram revealed no signs of recurrence.Discussion: HC has non-specific presentations. Radiologists, pathologists, and surgeons should consider HC as a differential diagnosis for any cystic mass in the pelvic cavity, especially in endemic areas. Surgical resection and albendazole administration are the chosen treatments.
