PURPOSE: To report a case of an adult with a ciliary body mass diagnosed as a medulloepithelioma by fine-needle aspiration, confirmed by tissue biopsy, and successfully treated with brachytherapy. DESIGN: Interventional case report. METHODS: A 23-year-old white woman presented with a large mass originating in the ciliary body of the left eye. The mass, which measured 6 × 5 × 7.6 mm, was at the upper limits for resection. Treatment with iodine-125 brachytherapy (4,648 cGy) was employed to debulk the mass before eyewall resection. RESULTS: The elevation of the mass by ultrasonography 5 months after brachytherapy was 3.9 mm with no evidence of growth during the 18-month follow-up period. CONCLUSION: We report a case in which a ciliary body medulloepithelioma treated with brachytherapy had a favorable response through 18 months of follow-up after treatment. This is a single case report, and longer follow-up is necessary before treatment efficacy can be fully evaluated.
