Abstract

Autoimmune pancreatitis (AIP) is rarely associated with pancreatic pseudocysts. AIP-associated pseudocysts requiring drainage despite steroid therapy are rather rare. We report a case of AIP with an infected pseudocyst requiring drainage despite steroid therapy. A 68-year-old male was diagnosed with AIP via pancreatic imaging, a high serum immunoglobulin G4 level, and steroid responsiveness. The AIP was accompanied by a pancreatic pseudocyst. Steroid therapy was prescribed, but the pancreatic pseudocyst became aggravated during steroid tapering. Endoscopic ultrasonography-guided cyst drainage was required; the pseudocyst then became completely resolved.
