Imaging: MRI with MRCP
The cholangiographic findings of IgG4-related sclerosing cholangitis (IgG4-SC) are heterogeneous and can mimic other biliary diseases, making it difficult to diagnose IgG4-SC on the basis of biliary changes on cholangiography alone [1–3]. MRI with MR cholangiopancreatography (MRCP) can simultaneously provide imaging of wall thickening of the bile ducts and its enhancement patterns, the pattern and degree of biliary strictures, and other IgG4-related disease in different intra-abdominal organs, such as autoimmune pancreatitis, IgG4-related renal disease, and retroperitoneal fibrosis . Therefore, MRI with MRCP is a useful noninvasive diagnostic tool for IgG4-SC.
