Figure 14. A 25-year-old woman presented with fever and abdominal tenderness 2 days following penetrating trauma in the right upper quadrant (RUQ). Contrast-enhanced CT shows gallbladder (GB) wall thickening (asterisk) with intraluminal bile-blood level (arrowhead), infiltration within the posterior pericholecystic tissue (black arrow) and the RUQ subcutaneous defect (white arrow) indicating the stab wound. At surgery two lacerations were found within the anterior and posterior aspect of the GB with mild biliary peritonitis.
