Toxic adenoma in childhood--case report

A 12-year-old girl was noted to have a left sided thyroid nodule on routine examination. Although clinically euthyroid she was found to have an elevated T3 value, and the TSH failed to rise following TRH injection. Thyroid scan showed a hyperfunctioning nodule in the left lobe of the thyroid gland. Following surgical removal of the nodule the patient became biochemically euthyroid and a repeat thyroid scan demonstrated the previously suppressed normal right lobe.
