Exploring rare locations of hydatid disease: a retrospective case series

Hydatid disease, endemic in Mediterranean countries, primarily affects the liver, but can manifest in diverse organs. Non-hepatic and non-pulmonary cysts often pose diagnostic challenges. This study examines patients with hydatid cysts in atypical locations. From 2013 to 2020, our center treated 250 echinococcosis patients, among whom 11 cases (4.4%) with hydatid disease in uncommon sites were retrospectively reviewed. The distribution of unusual cyst locations and their clinical implications are discussed. Diagnosing hydatid cysts in uncommon locations is a formidable challenge. Surgeons should always contemplate the prospect of an unconventional cyst location when encountering patients with cystic masses in endemic regions. Failing to consider this possibility could lead to unfavorable outcomes.
