Eosinophilic cholecystitis is a rare post-cholecystectomy inflammatory histopathological condition characterized by more than 90% eosinophilic infiltrate in the gallbladder. We present a case of 27-year female presented with abdominal pain, fever, jaundice, altered mental status, shock, leucocytosis, deranged liver function test, and peripheral blood eosinophilia. The patient underwent cholecystectomy and common bile duct exploration. She developed adult respiratory distress syndrome and hospital-acquired pneumonia. From this, we want to emphasize that eosinophilic cholecystitis and cholangiopathy should be a differential diagnosis in patients presenting with allergy, peripheral eosinophilia, obstructive jaundice that are planned to undergo cholecystectomy that will have early critical care intervention.
