ABSTRACT

We describe a case of ectopic thyroid nodular hyperplasia, which mimicked a lymph node metastasis from a primary occult thyroid carcinoma. 50-year female was admitted to our clinic because of anterior mediastinal mass. On physical examination, there was a single, non-tender, firm swelling situated in the left supraclavicular region. Contrast-enhanced neck-chest CT showed about 5 cm-sized heterogeneous mass being strongly suspicious to malignancy such as a thymic carcinoma. PET-CT also revealed a circular lesion accompanied partially intense FDG uptake at the inferolateral area of left thyroid. Excision of the tumor was performed. Conventional biopsy proved a ectopic thyroid nodular hyperplasia which could mimic a metastasis of the thyroid carcinoma. Being aware of the possibility ectopic thyroid nodular hyperplasia is important so that unnecessary surgical assessment and undesirable sequelae should be avoided.
