A rare case of primary tubo-ovarian hydatid cyst, Approved pathologically and molecularly

Echinococcus granulosus (sensu lato) is the main cause of cystic hydatid in human and livestock in the world and is considered a neglected tropical disease. Hydatid cysts often form in the liver (50–70%) and less frequently the lung, spleen, kidney, bone, brain and genital system. Ovarian hydatid cyst is one of the rarest cases with nonspecific clinical presentation. Here in a case report study we report a primary unilateral ovarian hydatid cyst in a 45-years-old woman. This patient was presented with a large pelvic mass. A pelvic multiloculated mass in abdominal ultrasound and a solid-cystic lesion of the left adnexa in CT scan was reported. All other laboratory tests and chest X-ray showed typical results. Molecular method was performed to confirm radiography and staining methods. A cystic mass on the left fallopian tube and ovary was found in the patient's laparotomy and all were resected with the appearance of a tubo-ovarian abscess. Postoperative pathological and molecular diagnosis confirmed a hydatid cyst disease. Five years follow-up revealed no recurrence of the disease. Hydatid cyst can cause cystic masses anywhere in the all anatomic of body, especially in endemic locations.
