Recent advancement in radiological imaging has revealed an increasing amount of asymptomatic abnormalities. Tracheal diverticula are relatively rare entities and are incidentally found on radiological imaging such as computed tomography. Here, we present a case of an infected tracheal diverticulum presenting as a paratracheal mass, which required emergency intervention.
A 65-year-old Japanese nonsmoker man presented with a fever, lower neck pain, and the aggravation of dyspnea for a week. An enhanced computed tomography scan demonstrated that the trachea was displaced by a paratracheal mass with a well-defined thin wall. His respiratory status was so urgent that emergency intubation and surgical drainage of the abscess were performed. A computed tomography scan performed 4days after admission demonstrated shrinking of the abscess, and he was extubated and discharged 7days after admission without any complications.
To the best of our knowledge, this is the first report to confirm an infected tracheal diverticulum presenting as a paratracheal abscess, which required emergency intervention. Moreover, computed tomography plays an important role in the differentiation of paratracheal masses.
放射影像学的最新进展显示，无症状异常的发现数量不断增加。气管憩室相对罕见，通常在计算机断层扫描等放射影像学检查中偶然发现。在此，我们报告一例以气管旁肿块形式出现的感染性气管憩室病例，该病例需要紧急干预。
一名65岁的日本男性非吸烟者，出现发热、下颈部疼痛和呼吸困难加重一周。增强计算机断层扫描显示，气管被一个薄壁清晰的气管旁肿块推移。他的呼吸状况非常紧急，因此进行了紧急插管和脓肿手术引流。入院4天后进行的计算机断层扫描显示脓肿缩小，他在入院7天后拔管出院，无任何并发症。
据我们所知，这是第一例证实以气管旁脓肿形式出现的感染性气管憩室并需要紧急干预的报告。此外，计算机断层扫描在气管旁肿块的鉴别诊断中起着重要作用。
