Multiple Disseminated Hydatidosis with Rare Locations: Mediastinal, Pancreatic and Pelvic (Case Report)

Abstract

Hydatid disease is an anthropozoonosis due to the development of the larval form of Echinococcus granulosus in the human body, which constitutes a ‘dead-end’ host. It’s a common parasitosis in North African countries and constitutes a public health problem in Morocco. The liver and lung are the most affected while the mediastinum, pancreas and pelvis are rarely affected. We report the case of a 40-year-old patient operated 15 yearsago for cerebral and cervical hydatid cysts and who was hospitalized for  generalized mucocutaneous jaundice. On exploration, we discover the presence of disseminated abdominal hydatidosis with association of 3 rare locations: mediastinal, pancreatic and pelvic. Indirect diagnostic tests were positive: indirect hemagglutination (IHA) and Elisa. The Western blot test also showed the presence of specific bands, thus making it possible to retain the diagnosis of hydatidosis. The hydatid cyst with mediastinal, pancreatic and pelvic location is rare and their association is very exceptional. It is essential to evoke the hydatid origin of any cystic lesion in a patient staying in an endemic area.
