Management of medulloepithelioma of the ciliary body with brachytherapy.

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 x 5 x 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.
