(a) Contrast enhanced CT shows a distended gallbladder (GB) with "sandwich-like" mural thickening, pericholecystic stranding of inflammatory changes and indistinct interface between the GB and the adjacent liver (arrows). (b) 2 cm caudally to (a), marked pericholecystic inflammatory changes (arrowheads) are seen with reactive thickening of the adjacent duodenum (D).
