Abstract
Autoimmune pancreatitis (AIP) is a rare disorder frequently manifesting as a mass-like lesion that may lead to obstructive jaundice. We report here a case of pancreatic obstruction with painless jaundice, and elevation of CA 19-9 without elevation of serum IgG4. Contrast enhanced ultrasonography (CE US) revealed the possibility of AIP, and the final pathological findings confirmed the diagnosis.
