Hydatid Disease of the Pelvis: A Rare Manifestation With Diagnostic Challenges—A Case Report and Comprehensive Literature Review

Hydatid disease, a parasitic infection caused by a tapeworm of the genus Echinococcus, predominantly affects the liver and the lungs, but its location in the pelvis is extremely rare. Pelvic hydatid cysts can sometimes mimic as an adnexal mass and can pose a significant diagnostic challenge, with subsequent delays in the treatment. We herein aim to highlight the importance of considering hydatid disease in the differential diagnosis of a pelvic cystic lesion, especially in endemic regions, to avoid misdiagnosis and intraoperative complications, ensuring timely treatment and reduced morbidity.
