Granulosa tumor simulating a secondary localization hydatid cyst

The location of hydatid cysts in the pelvis as a secondary site is rare and misleading, with a disconcerting clinical symptomatology. Preoperative diagnosis of pelvic hydatidosis is sometimes difficult, and should be considered in the presence of any pelvic mass, especially in endemic countries. However, misleading cystic forms do exist, and differential diagnoses other than secondary localizations of hydatid cysts may be observed. We report a case of an adult granulosa tumor mimicking a secondary pelvic localization in a patient with a hydatid cyst of the liver
