A CASE OF MULTIPLE BRONCHOGENIC CYSTS

Mediastinal tumor is a disease that we usually experience in general practice. We present a rare case of double bronchogenic cysts which originated from the paraesophageal and paratracheal regions. A 51-year-old man was admitted to the clinic because of an abdominal shadow on a chest X-ray film at a screenign examination. Chest X-ray films on admission revealed a clear tumor shadow at the right upper mediastinum. In addition, a clear soft tissue mass 3cm in diameter was demonstrated at the right upper mediastinum on a chest CT scan. On magnetic resonance imaging (MRI), two tumors with the size of 4cm at the right upper mediastinum were separately found. High signal intensity was shown on Tl-weighted images and very high signal intensity on T2-weighted images in both tumors. Enhancement effect by Gadolinium was not found. Therefore, the tumors were suspected of cystic mass. It was easy to remove both tumors. The cysts contained a kind of jelly like mucus. Both tumors were diagnosed as bronchogenic cyst by pathological examination. We would emphasize that esophageal lesion of the neck was found by chest MRI (coronal view) in this case. We have to examine preopertively by paying consideration to possible multiple occurrence of bronchogenic cysts.
