title: [A case report of a paraesophageal bronchogenic cyst and an esophageal cyst].
abstract: There are relatively few paraesophageal bronchogenic and esophageal cysts in mediastinal tumors. It is often difficult to distinguish between these cysts. Case 1: 11 year old, male with no symptoms. An abnormal tumor shadow was revealed by chest roentgenogram. Before operating, CT, MRI and other laboratory tests were suggested that the tumor was neurogenic. A cyst with a pedicle connected to the esophageal muscle layer was found during the operation. Pathological examination confirmed a bronchogenic cyst lined with cartilage. Case 2: 38 year old female with epigastralgia. Upper gastrointestinal series revealed that the thoracic esophagus was smoothly compressed from the outside. CT and MRI showed a well-defined cystic mass in the posterior mediastinum. The cyst bordered the esophagus, but there was no direct communication between them. The pathological findings showed the presence of a double layer of smooth muscle without cartilage which was diagnosed as an esophageal cyst.
