The development of a solitary toxic thyroid nodule following Graves' disease.
A 52-year-old woman developed a toxic, solitary, autonomously functioning thyroid nodule four years after antithyroid drug treatment for Graves' disease. When she was initially seen, a thyroid scan showed the homogeneous enlargement of both lobes with increased uptake. Graves' disease was diagnosed and the patient was treated with methimazole. Thyroid function was well-controlled with medication for 18 months, after which the patient stopped taking the drug for three years. Four years after Graves' disease was diagnosed, the patient again showed symptoms of hyperthyroidism. The etiology was a toxic, autonomously functioning nodule.
