Description

A 21-year-old asymptomatic man was admitted to the hospital with an abnormal shadow on chest X-ray films, which was suspected to be a mediastinal mass. CT scan, MRI and endoscopic ultrasonography showed a cystic tumor in the right superior mediastinum adjoining the right wall of the trachea. A bronchogenic cyst was suspected, and anteroaxillary thoracotomy was performed on November 12, 1991. The cyst was located in the superior mediastinum, above the azygos vein, posterior to the superior vena cava and connected to the thoracic duct. It was easily removed by blunt and sharp dissection after ligation and division of the thoracic duct. The cyst was 55 × 35 × 30 mm in size, had a thin wall and some trabecular structures in the lumen, and contained translucent yellow fiuid. Microscopically, Sudan III stain revealed fluid with numerous macrophages containing fat droplets. His postoperative course was uneventful, and he was discharged from the hospital on the sixth postoperative day.
