Orbital lesions may be the presenting sign of a systemic disease, such as a metastatic cancer. A metastatic cancer of the orbit, which has been reported to account for 2~3% of all orbital tumor, is a malignant neoplasm that had spread by hematogenous routes to the orbit from a distant primary site. Although metastatic orbital tumors are mostly from breast, lung, prostate, rarely, they can be originated from gastrointestinal tract such as large intestine, ileum and pancreas. However, there has been no report of metastatic orbital tumor from biliary system, until now. Herein, we report a unique case of metastatic orbital tumor from the intrahepatic cholangiocarcinoma, which has been successfully controlled with systemic chemotherapy and radiotherapy.
