Figure 1 The ultrasound and computed tomography images of pancreas and gallbladder. A: The pancreas is diffusely enlarged with unclear boundary and the parenchyma echo is reduced; B: The gallbladder volume is enlarged and the wall is rough, accompanying with the silt-like deposits; C: The pancreatic lesions area is uniformly enhanced in arterial phase after the intravenous ultrasound contrast-enhanced; D: Contrast-enhanced computed tomography image revealing that both the pancreas and gallbladder are enlarged and the gallbladder wall is thickened, which are consistent with the ultrasound results.
