title: Extrapancreatic findings of IgG4-related disease.
abstract: IgG4-related disease is a systemic fibro-inflammatory condition, which includes autoimmune pancreatitis as part of the disease spectrum. Imaging has been demonstrated to play a major role in the diagnosis of autoimmune pancreatitis. Recognizing the wide spectrum of extrapancreatic manifestations of IgG4-related disease coupled with a high clinical index of suspicion will allow for an accurate and timely diagnosis to be made, thus avoiding unnecessary invasive procedures and ensuring that early effective corticosteroid therapy is commenced. This review aims to serve as a concise reference tool for both clinicians and radiologists in the diagnosis of extrapancreatic IgG4-related disease.
