Ovarian Carcinoma Uncloaked by Hydatidosis: An Intraoperative Epiphany.

Hydatidosis is an infective ailment that is caused by the parasite echinococcus granulosus. The parasitic infection typically produces cysts filled with excessive quantity of fluid and most commonly afflicts the liver. While secondary hydatidosis remains exceedingly rare, cases of hydatidosis in organs such as the ovaries and the fallopian tubes have been documented in the literature. In such instances, the patients present with a vague constellation of symptoms, including abdominal distension and vague abdominal pain. Herein, we elucidate the case of a female patient who presented with massive abdominal swelling on a background history significant for hydatid liver disease. Intraoperative findings included a left adnexal mass, which was eventually established to be an ovarian adenocarcinoma coexisting with secondary ovarian hydatidosis.
