Key words: Thymic hyperplasia, Graves’ disease, Case report
The case of a 10-year-old girl with clinical hypothyroidism in substitution treatment is described. After the onset of symptoms suggestive of mediastinal mass associated with evolution in hyperthyroidism, she was diagnosed with thymic hyperplasia in Graves’ disease. The mass regressed after antithyroid treatment. Thymic hyperplasia is a benign condition that can be associated with Graves’ disease even if symptomatic massive enlargement is rare. The pathogenesis is not well understood. Antithyroid drugs usually lead to regression, therefore a correct diagnosis by using imaging techniques (echography, MRI, and CT), is essential to avoid unnecessary surgical procedures.
