Abstract

True primary mediastinal ectopic goiters are quite rare, occurring in less than 1% of all goiters. Ectopic thyroid tissue in embryonic development is the result of abnormal migration of the thyroid gland as it travels from the floor of the primitive foregut to its pretracheal position. We report a case of 54 year old male. He suffered from chest pain, cough and dyspnea on exertion. His medical history had hypertansion and aortic aneurism and no additional disoders. On physical examination thyroid was not palpable. Serum thyroid tests and thyroid nuclear scans were normal. There was a mass lesion on computerized thorax thomography in azygos-caval junction, 45x42mm in size, smooth circumference. There was no endobroncial lesion on fiber optic bronchoscopy. Standart servical mediastinoscopy was performed in order to diagnosis. Pathology reported as a benign thyroid tissue. Because of compression on vena cava superior we resected completly this tumor via right lateral thoracotomy. Postperative period was uneventful. Postoperative pathology was reported also benign thyroid tissue. We present an uncommon true primary ectopic mediastinal goiter resected with complete excison in order to relief of symptoms and to prevent potential venous obstruction and malignant transformation.
