• An exhibit of the multimodality US/CT/MRI/fluoroscopic imaging characteristics of autoimmune pancreatitis to aid in the differentiation of AIP from malignant pancreatic processes. • To illustrate other extra-pancreatic imaging features. • The role of imaging in follow up after treatment with steroids.

Autoimmune pancreatitis (AIP) is the pancreatic manifestation of IgG4 related sclerosing disease which was recently recognized as distinct disease entity. Known as a benign disease process, it can clinically mimic pancreatic cancer. Early diagnosis and management is important as it can slowly progress to end stage pancreatic disease. Numerous extrapancreatic organs may be involved either synchronously or metachronously. Most cases of AIP are associated with elevated IgG4 levels; extensive...

AIP is a clinical entity frequently recognized in the radiology community. Patients often present with obstructive jaundice and can be misdiagnosed with pancreatic cancer. It is important to recognize this disorder, its extra-pancreatic processes and promptly commence steroid therapy to avoid end stage pancreatic disease and surgery. A multi-modality imaging approach can support a clinical and biochemically suspected diagnosis.
