The ultrasound image shows an adequately distended gallbladder with sludge layering in the dependent portion of the gallbladder. An ill-defined gallstone with posterior acoustic shadow in seen near the fundus of the gallbladder. Gallbladder wall is slightly thickened. There is a trace amount of pericholecystic fluid seen. Sonographic Murphy sign was positive. There is evidence of echogenic air within/or just under the anterior wall of the gallbladder. The air also has associated reverberation artifact and other air pocket has a dirty shadow seen posteriorly. In this case it would be difficult to comment with certainty if the air is due to emphysematous cholecystitis or due to the ERCP procedure. Perform serial follow up ultrasound exams and correlate clinically. In this case air was accidentally introduced during ERCP and papillotomy.
