Imaging diagnosis of autoimmune pancreatitis / 临床肝胆病杂志

ABSTRACT

Autoimmune pancreatitis (AIP) is a special autoimmune-mediated pancreatitis with the clinical manifestation of obstructive jaundice, and it often has good response to steroids. At present, AIP is classified into type 1 and type 2. The imaging findings of AIP include diffuse or localized pancreatic parenchymal enlargement, and the former is also called the “sausage-shaped” appearance. Imaging examinations of AIP have their own advantages and disadvantages. Ultrasound, endoscopic retrograde cholangiopancreatography, endoscopic ultrasound, computed tomography, magnetic resonance imaging, PET-CT, and PET-MR help with diagnosis and differential diagnosis and can be used for the monitoring and follow-up of clinical outcomes.
