Abstract
Choroidal metastases are the most common intraocular malignant tumors in adults [1]. Because of its large vascular network, the choroid is the most frequently involved ocular layer. The majority of patients with choroidal metastasis have been previously diagnosed with systemic cancer. In one-third of the patients, the choroidal metastasis is found before the primary tumor [1]. Breast (45%) and lung cancer (25%) are the most common primary neoplasms [1]. The gastrointestinal tract (4%), in particular, the rectum (< 0.5%), is an unusual site of origin [1], [2].
