ABSTRACT: Background: Immunoglobulin G4-related pancreatitis (IgG4-RAIP) is a relatively rare chronic inflammatory disease of the pancreas. The cause of this disease is still unclear. Due to the lack of specific clinical symptoms and imaging findings, it is often misdiagnosed as pancreatic cancer. Clinicians are paying more and more attention to it. Case report: We are reporting an IgG4-RAIP case, in which the patient had been misdiagnosed as pancreatic cancer and prepared for surgical treatment but finally was diagnosed as IgG4-RAIP after pancreatic biopsy and serum immune test. And the patient was recovered after the treatment of glucocorticoids. Discussion: In order to make more patients get correct diagnosis and reasonable treatment, when we encounter undiagnosed cases of pancreatitis or pancreatic cancer in clinical work, it is very important to conduct pancreatic biopsy and serum immune blood test before operation for these patients. Conclusion: Pancreatic biopsy and serum immune blood test can effectively reduce the occurrence of misdiagnosis of IgG4-RAIP.
