Abstract
Introduction: Autoimmune pancreatitis (AIP) and pancreatic cancer are top differentials of obstructive jaundice originating from the pancreas. Case Description/Methods: The patient's findings were concerning for malignant biliary obstruction, but a thorough workup determined that the patient had AIP-NOS. She underwent EBS and was discharged on a steroid taper. Follow-up demonstrated complete resolution of symptoms, laboratory markers, and imaging. Conclusion: Adequate pancreatic tissue is not always obtained with 22-gauge needles. Biliary stenting is justifiable in AIP with significant hyperbilirubinemia. It is important to consider AIP for with a pancreatic head mass and obstructive jaundice to optimize outcome.
