Thyroid Tuberculosis Presenting as a Cystic Nodule

Abstract Although tuberculosis involves every organ and has a wide range of clinical manifestation, however involvement of the thyroid gland is rare. We report a case of a 25-yr-old female with supraclavicular lymphadenitis that developed nodular swelling of the thyroid and had symptoms and sonographic features mimicking a nodule with a cystic component. The diagnosis was made by using fine needle aspiration (FNA). We conclude that thyroid tuberculosis should be considered in the differential diagnosis of thyroid nodules and that FNA can be the main diagnostic procedure.
