ABSTRACT: Autoimmune pancreatitis (AIP) is a unique form of
pancreatitis which has autoimmune features. AIP has clinical presentations that greatly mimic pancreatic cancer (PC).
It is critical for clinicians to distinguish AIP from PC because their
treatments and prognoses are entirely different. We report a 62-year-old man with
obstructive jaundice and dilation in the main pancreatic duct (MPD). The diagnosis of AIP
was based on diagnostic criteria by the elevated IgG-4 serum levels and the
typical imaging such as diffuse pancreatic swelling and dilation in the common
biliary duct (CBD). The difference of the imaging finding in our case is the expanding of the MPD, which is usually described to be stenosis in many literatures. Finally, the patient was confirmed with type I AIP according to the diagnosis
criteria. After the steroid treatment lasting 3 months, the patient was gradually recovered. We present the case and take a review of literature in order to improve
the early identification of AIP.
