A 52-year-old man presented with painless jaundice and weight loss. A computed tomography (CT) scan of the abdomen revealed an inflammatory mass in the pancreatic head. Endoscopic retrograde cholangiopancreatography (ERCP) demonstrated a double duct sign ([Fig. 1]), and a biliary stent was placed. Brush cytology was negative and percutaneous biopsy showed inflammatory changes. Laparotomy confirmed a large inflammatory mass in the pancreatic head, and a cholecystojejunostomy was carried out. Several months later, the patient developed recurrent jaundice and ERCP showed new diffuse strictures involving the intra- and extrahepatic biliary tree ([Fig. 2]). CT abdomen revealed concentric thickening of the common bile duct (CBD) with enlarged periportal nodes ([Fig. 3]), and endoscopic ultrasound with fine-needle aspiration biopsy of the pancreatic head and lymph nodes was benign. A liver biopsy showed bile duct inflammation and marked cholestasis, and ultrasound revealed patent vasculature. Colonoscopy as well as autoimmune serology and IgG4 levels were normal.
A diagnosis of secondary autoimmune pancreatitis associated sclerosing cholangitis (AIP-SC) was considered. The patient was prescribed steroids and methotrexate. Several months later ERCP showed marked improvement of the biliary tree ([Fig. 4]). Over the next 5 years, the patient was maintained on azathioprine 100 mg daily, with normal liver enzymes. On tapering the azathioprine to 50 mg daily, he developed acute cholangitis. ERCP showed stricturing of the extrahepatic biliary tree requiring balloon dilation and stenting ([Fig. 5]). The patient was restarted on a prednisone taper and azathioprine 75 mg daily, with marked improvement seen on a cholangiogram taken 3 months later ([Fig. 6]). The patient is currently well with normal liver enzymes and is taking 75 mg azathioprine daily.

Clinicians should be aware that AIP-SC can mimic pancreatic cancer. In addition, sclerosing cholangitis can complicate AIP, particularly after biliary bypass surgery [1] [2]. Until the etiology, pathogenesis, and natural history have been defined more precisely, no definite recommendations with respect to medical therapy can be made. However, treatment with corticosteroids and/or other immunosuppressive therapy can be effective in patients presenting with this entity [3].
