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

TL;DR

A rare case of a primary ovarian hydatid cyst was reported, initially mistaken for a cyst adenoma but later confirmed through surgery and treatment.

Contribution

This case report highlights the diagnostic challenge of hydatid cysts in the ovary and emphasizes the importance of considering them in differential diagnosis.

Findings

A 47-year-old woman presented with a pelvic cystic mass initially thought to be a cyst adenoma.

Histopathological examination confirmed the mass as a hydatid cyst, and treatment with albendazole prevented recurrence.

The case underscores the need for HC to be considered in differential diagnoses of pelvic cystic masses in endemic regions.

Abstract

Hydatid cysts (HC) are zoonotic diseases that are mainly caused by Echinococcus granulosus. Ovarian HC is a rare condition with different and unspecified presentations. Here we report a rare case of primary ovarian HC.

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.

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.
