Abstract

Choroidal metastasis from rectal cancer is a rare occurrence with limited literature on appropriate evidence-based treatment options. We describe the case of 44-year-old man who presented with left-sided painful vision loss who was found to have left choroidal and multiple lung metastasis from an unknown primary which was later found to be rectal adenocarcinoma.

Learning points: Ocular metastasis from colorectal cancer is rare with choroid being the most common site of involvement if it occurs.Ocular metastasis usually occurs as a part of generalized metastasis to multiple organ systems.Treatment options include systemic chemotherapy, radiation, bevacizumab and enucleation.

Keywords: Rectal adenocarcinoma; case report; choroidal metastasis; colorectal cancer; ocular metastasis.
