Abstract
- Choroidal metastasis from colorectal cancer is very rare and has not been reported before in Korea. We report a case of eye hyperemia and discomfort in a patient with advanced colon cancer. Orbit magnetic resonance imaging and positron emission tomography revealed an enhancing mass within the temporal side of the left orbit, suggestive of choroidal metastasis from the colorectal adenocarcinoma. The condition's rarity may be due to the long and distant pathway from the colon to the orbit. The presentation usually suggests extensive hematogeneous cancer dissemination and a poor prognosis. However, palliative radiotherapy may be an effective treatment for choroidal metastasis.
