CT findings of acute cholecystitis and its complications

Abstract

Objective: The purpose of this article is to describe and illustrate the CT findings of acute cholecystitis and its complications.

Conclusion: CT findings suggesting acute cholecystitis should be interpreted with caution and should probably serve as justification for further investigation with abdominal ultrasound. CT has a relatively high negative predictive value, and acute cholecystitis is unlikely in the setting of a negative CT. Complications of acute cholecystitis have a characteristic CT appearance and include necrosis, perforation, abscess formation, intraluminal hemorrhage, and wall emphysema.
