Ascaris Lumbricoides uncommonly presents as a cholecystitis due to anatomical considerations. Despite that, it presents in 2.1% of the hepatobiliary ascariasis. Patients usually have vague symptoms of abdominal pain sometimes with fever, mimicking cholecystitis. Ultrasonography (USG) helps in initial diagnosis. We present a case of 50 years old female with gallbladder ascariasis for which cholecystectomy was done successfully.
