Eosinophilic cholangitis (EC) is an uncommon, benign, self-limiting disease, which typically causes bile duct stricture with eosinophil infiltration. We report the case of a 70-year-old woman who presented with abdominal pain diagnosed with EC after treatment for eosinophilic esophagitis. All previous reported cases of EC had bile duct stricture seen on magnetic resonance cholangiopancreatography or cholangiogram during endoscopic retrograde cholangiopancreatography, but only wall thickness of the common bile duct was noted in our case. Although rare, EC should be considered when wall thickening of the bile duct is observed, even without stricture.
