A 57-year-old male was admitted for evaluation of an abnormal shadow in the right upper mediasinum of his chest X-ray. His chief complaints was nocturnal dyspnea. Chest CT and MRI showed tracheal compression due to a cystic mass in the right paratrachea, which compressed the brachiocephalic trunk and the right common carotid artery. Bronchofiberscopy showed marked stenosis of the trachea. He underwent a median sternotomy with a right half collar incision, and the cystic tumor was removed. The cyst had no communication with the pericardial cavity. The size of the resected specimen, filled with serum, was 7 × 6 × 5 cm. Histopathological examination of the specimen showed a mesothelial-lined structure overlying a thin layer of fibrous tissue. After the course of surgical treatment, lung function improved remarkably compared to the preoperative state.
