[A case of ascending aortic aneurysm with intrathoracic goiter].

A case of the successful operation for ascending aortic aneurysm and intrathoracic goiter was described. A 71-year-old woman was admitted to our hospital for the treatment of ascending aortic aneurysm disclosed by the examination in another hospital. Preoperative chest CT showed ascending aortic aneurysm as large as 8 cm in diameter, and an upper mediastinal tumor compressing the main bronchus. The tumor was continuous with the right lobe of the thyroid. The excision of the tumor was performed through median sternotomy with cervical collar incison. After that, the replacement of the ascending aorta was carried out under cardiopulmonary bypass and hypothermic circulatory arrest. The histological examination of the resected specimen revealed adenomatous goiter without malignancy.
