A 65-year-old woman presented with pain in her throat and neck. Thin-section computed tomography (CT) revealed an air-filled lesion at the right paratracheal region and two narrow connections to the trachea. Flexible bronchoscopy showed four diverticula 4-5 cm below the vocal cords in the right lateral part of the trachea. Consistent with the CT findings, two of the diverticula were deep. A radiological barium swallow study and an esopagogastroduodenal endoscopic examination revealed no abnormalities. We therefore believe that her right paratracheal air cyst is an extension of a tracheal diverticulum. Right-sided paratracheal air cysts at the level of the thoracic inlet are a common finding on CT and should not be confused with pneumomediastinum in order to avoid unnecessary examinations or treatments.
一名65岁女性因咽喉和颈部疼痛就诊。薄层计算机断层扫描（CT）显示右气管旁区域有一个含气病变，与气管有两个狭窄连接。可弯曲支气管镜检查显示在气管右侧部分声带下方4 - 5厘米处有四个憩室。与CT结果一致，其中两个憩室较深。放射学钡餐检查和食管胃十二指肠内镜检查未发现异常。因此，我们认为她的右气管旁气囊肿是气管憩室的延伸。胸廓入口水平的右侧气管旁气囊肿在CT上是常见表现，不应与纵隔气肿混淆，以免进行不必要的检查或治疗。
