Abstract: Eosinophilic Cholangitis (EC) is a rare, benign disease often mistaken for cholangiocarcinoma as
clinically and radiologically EC resembles cholangiocarcinoma. Often, extensive hepatobiliary
resections for a presumed malignancy are completed; however, with appropriate diagnosis EC can
be managed medically. We present two cases of EC with a comprehensive literature review and a
proposed diagnostic decision algorithm for EC by which to evaluate suspicious lesions with biliary
obstruction and potentially avoid surgery for this benign disease.Keywords: biliary obstruction, benign liver disease, cholangiocarcinoma, diagnostic algorithm, malignant versus benign
