[Eosinophilic cholecystitis associated with rupture of hepatic hydatid cyst of the bile ducts]. / Colecistitis eosinofílica asociada a ruptura de un quiste hidatídico hepático en vías biliares.

Eosinophilic cholecystitis is a rare finding characterized by an inflammatory infiltrate composed primarily of eosinophils. We report a case of eosinophilic cholecystitis associated with hepatic hydatic cyst ruptured into the biliary tract. The release of hydatid cyst content into the biliary tract may have induced a hypersensitivity reaction with numerous eosinophils in the gallbladder wall.
