  		Figure 1. The gallbladder is grossly distended with poor definition of its walls. A large encapsulated low-attenuation collection within adjacent hepatic parenchyma shows internal loculation and a few air pockets. Multiple calculi are seen within both the gallbladder and the intrahepatic abscess. A rent in the lateral wall of the gallbladder (arrow) is seen.
