title: Extrapulmonary tuberculosis with paravertebral abscess formation and thyroid involvement.
abstract: Extrapulmonary tuberculosis has a broad spectrum of clinical manifestations. Involvement of the thyroid gland has rarely been reported. We report a case in a patient with a non-tender swelling of the thyroid, whose symptoms, sonographic and scintigraphic features mimicked carcinoma. Initially the patient presented with back pain due to a paravertebral mass. Fine needle aspiration and culture of the aspirate both from the paravertebral mass and the thyroid ensured the diagnosis. Although seldom observed, tuberculosis should be kept in mind in the differential diagnosis of nodular lesions of the thyroid. The preponderant absence of thyroid dysfunction in mycobacterial thyroiditis is confirmed by this case.
