[Pancreatic hydatid cysts].

Primary pancreatic hydatidosis is extraordinary rare with an incidence of less than 0.2 per 100 of the cases. We report a seven year old boy who comes to hospital with abdominal pain and tumor. Echography shows a six centimeters diameter multilocular cystic mass located in the tail of the pancreas. Other complementary data include eosinophilia (16 per 100), increased levels of IgE and specific immunofluorescent antibody titer of 1/6000.
