Contained gallbladder perforation in a patient with acute cholecystitis

Computed tomographic (CT) scan showing a sealed perforation of the gallbladder. Transverse (A) and reformatted coronal projections (B) of the CT scan demonstrate a focal accumulation of fluid near the fundus of the gallbladder (white arrowhead) with significant induration in the pericholecystic fat (yellow arrow). At surgery a necrotic and perforated gallbladder was identified.
