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

Figure 4 A 61-year-old man with dull right upper abdominal pain for 3 wk. A: US showed a relatively small gallbladder with focal wall thickening (arrows), which was misinterpreted initially as inadequate gallbladder distension; B: Contrast-enhanced CT was done because of persistent abdominal discomfort. It revealed relatively poor distension of the gallbladder with prominent enhancement of the focally thickened gallbladder wall (white arrows) and celiac lymph node metastasis (black arrow).
