A rare presentation of choroidal metastasis from primary esophageal adenocarcinoma successfully treated with intensity-modulated radiation therapy

PURPOSE: In this case report, we present a case of choroidal metastasis from a primary esophageal adenocarcinoma that was treated successfully with intensity-modulated radiation therapy. OBSERVATIONS: A 65-year-old male with known stage IV esophageal adenocarcinoma presented with a central scotoma in his left eye and was ultimately found to have a large choroidal metastatic lesion with overlying subretinal fluid. IMRT was administered over the course of four weeks, resulting in restoration of the patient's vision, regression of the metastatic lesion, and resolution of the subretinal fluid. As of 16 months following completion of radiation, there remains no evidence of choroidal recurrence or radiation-associated ocular complications. CONCLUSIONS: and Importance: To our knowledge, this is the first published case report of a choroidal metastasis from esophageal cancer responding durably to IMRT. IMRT should therefore be considered a viable treatment option for this rare disease.
