• We report the case of a 5-year-old hyperthyroid boy with normal serum T4 levels and elevated serum T3 levels. The findings are diagnostic of T3 thyrotoxicosis, a condition that has been very infrequently reported in childhood. We postulate that low dietary iodine intake may be an etiologic factor in some cases of T3 thyrotoxicosis.
