Imaging findings for autoimmune pancreatitis include pancreatic enlargement and duct narrowing. Absence of vascular encasement or calcification on CT and endoscopic US, along with biliary strictures on ERCP, are suggestive features.

Area of Science:

  • Radiology
  • Gastroenterology
  • Immunology

Background:

  • Autoimmune pancreatitis (AIP) is a rare inflammatory condition with potential for misdiagnosis.
  • Accurate imaging is crucial for differentiating AIP from other pancreatic pathologies.

Purpose of the Study:

  • To retrospectively analyze and define the characteristic imaging findings of autoimmune pancreatitis.
  • To identify key imaging features that aid in the diagnosis of AIP.

Main Methods:

  • Retrospective review of imaging data from 29 histopathologically confirmed AIP patients.
  • Utilized helical computed tomography (CT), magnetic resonance (MR) imaging with MR cholangiopancreatography (MRCP), endoscopic ultrasonography (US), and endoscopic retrograde cholangiopancreatography (ERCP).
  • Assessed pancreas morphology, ductal systems, and peripancreatic changes, correlating with serologic markers in a subset of patients.

Main Results:

  • CT revealed diffuse or focal pancreatic enlargement in most patients, with minimal peripancreatic inflammation and absence of calcification or vascular encasement.
  • MRCP demonstrated pancreatic duct strictures and sclerosing cholangitis-like appearances.
  • ERCP showed significant strictures of the common bile duct and pancreatic ducts, often with irregular narrowing.

Conclusions:

  • Suggestive imaging features of AIP include focal or diffuse pancreatic enlargement with minimal peripancreatic inflammation and lack of vascular encasement/calcification on CT/US.
  • Diffuse irregular narrowing of the main pancreatic duct with associated multiple biliary strictures on ERCP are highly indicative of AIP.
  • Imaging findings, particularly ductal changes, can improve diagnostic accuracy for autoimmune pancreatitis.
