Intraluminal versus infiltrating gallbladder carcinoma: Clinical presentation, ultrasound and computed tomography

Figure 5 A 78-year-old man admitted to the emergency room with right upper abdominal pain, fever and jaundice for 1 d. A: US showed a contracted gallbladder with a thickened wall (arrowheads) and multiple gallstones that obliterated underlying details, which mimicked chronic cholecystitis; B: Contrast-enhanced CT showed a relatively small gallbladder with uneven wall thickening (arrowheads), multiple gallstones and pericholecystic inflammatory stranding and fluid suggestive of gallbladder carcinoma (GBCA), with coexistent acute cholecystitis. Note the intercavoaortic and left para-aortic lymph node metastasis (white arrows).
