Abstract

It has been reported that annular pancreas should be evaluated for coexisting malignant tumors. However, no cases have been reported in which magnetic resonance cholangiopancreatography and endoscopic ultrasonography clearly demonstrated an annular pancreas complicated by bile duct carcinoma. We present a case that emphasizes the importance of magnetic resonance cholangiopancreatography and endoscopic ultrasonography in directly confirming a diagnosis of annular pancreas complicated by bile duct carcinoma.

Key words: Annular pancreas—Magnetic resonance cholangiopancreatography—Endoscopic ultrasonography—Bile duct carcinoma—Endoscopic retrograde cholangiopancreatography.
