Background
IgG4 autoimmune pancreatitis is characterized by extensive periductal infiltration of IgG4-positive lymphocytes, plasma cells, and storiform fibrosis. They correspond to 2 - 11% of chronic pancreatitis and are generated due to sclerosis of the bile ducts.
Educational Goals / Teaching Points
Describe the typical findings in tomography (CT) and magnetic resonance imaging (MRI) of autoimmune pancreatitis (AIP) due to IgG4, a rare pathology of chronic pancreatitis, which has different forms of presentation and can be a diagnostic challenge at the time of diagnosis. differentiate it from other entities such as pancreatic ductal adenocarcinoma and acute pancreatitis.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Pancreatic injury and irregular stenosis of the pancreatic duct are the imaging diagnostic elements.
Conclusion
Thanks to the radiologic characteristics that have been found in CT and MRI, autoimmune pancreatitis is no longer a diagnostic challenge, and can be resolved with an imaging study to provide adequate therapeutic management.
