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.
在纵隔肿瘤中，食管旁支气管源性囊肿和食管囊肿相对较少见。区分这些囊肿往往很困难。病例1：11岁男性，无症状。胸部X线片显示有异常肿瘤阴影。术前CT、MRI及其他实验室检查提示该肿瘤为神经源性。手术中发现一个有蒂与食管肌层相连的囊肿。病理检查证实为内衬软骨的支气管源性囊肿。病例2：38岁女性，上腹部疼痛。上消化道造影显示胸段食管被外部平滑压迫。CT和MRI显示后纵隔有一个边界清晰的囊性肿块。该囊肿与食管相邻，但它们之间没有直接相通。病理结果显示有双层平滑肌且无软骨，诊断为食管囊肿。
