1- Review clinicopathologic spectrum of IgG4-related disease. 2- Discuss spectrum of imaging and pathologic findings in IgG4-related disease. 3- Review mimics with emphasis on key findings differentiating these entities.  

Content Outline: 1- Review key clinical, pathological, imaging findings and treatments of IgG4-related disease including: Autoimmune pancreatitis Sclerosing Cholangitis Sclerosing messenteritis Interstitial Nephritis Retroperitoneal fibrosis Coagulopathy 2- Review mimics of IgG4-related disease and highlight key imaging findings that aid in narrowing the differential: Pancreatitis (alcohol, cholithiasis, groove pancreatitis, neoplasm) PSC Messenteric and Retroperitoneal Neoplasms (Lymphoma/Leukemia/etc). Nephritis (glomerulonephritis, ATN, pyelonephritis, neoplasmetc) Vasculitis Summary: IgG4-syndrome involves multiple organs and can present in a vareity of ways. Although the differential diagnosis is broad, it can be narrowed utilizing clinicopatholgic features and imaging findings (e.g. Location, enhancement pattern, necrosis, MRI findings, etc). By the conclusion of this presentation, the viewer should be able to aid in patient work-up, recommend appropriate imaging follow-up and guide any potential biopsy.
