ABSTRACT
Objective To summarize the manifestation of autoimmune pancreatitis (AIP) on ultrasound and contrast-enhanced ultrasonography (CEUS).MethodsThe 2D ultrasound and CEUS images of 16 patients With AIP were retrospectively analyzed.Results On 2D ultrasound,AIP presented as diffusely(15 cases) or focally (1 case)swelling with low echo.13 cases revealed dilatation of the biliary tract.The choledochal wall showed thickening with a sandwich-pattern in 9 cases,which was also shown in 3 intrahepatic bile ducts and 3 gall bladders.On CEUS,6 AlP of diffuse form enhanced simultaneously and homogeneously.1 AIP with enlarged pancreatic head enhanced simultaneously,the enhanced degree in pancreatic head was higher than that of the surrounding pancreatic tissue in the vascular phase and equal to that in the parenchymatous perfusion phase.1 AIP of focal form enhanced slightly late compared with normal pancreatic tissue and the enhanced degree was lower in the vascular phase,while in parenchymatous perfusion phase.the pancreatic tissue enhanced homogeneously.ConclusionsThe manifestation of AIP on ultrasound and CEUS had some features which were helpful in diagnosis of AIP.
