Zenker's diverticula are esophageal outpouchings in the region of the cricopharyngeus which typically grow in a posterolateral and inferior direction and can cause esophageal compression if the diverticulum is large enough. We describe a patient in whom a Zenker's diverticulum expanded posteriorly and superiorly so that it was positioned in the posterior pharyngeal space, causing both esophageal and tracheal narrowing.
Zenker憩室是环咽肌区域的食管外突，通常向后外侧和下方生长，如果憩室足够大，可导致食管受压。我们描述了一名患者，其Zenker憩室向后上方扩展，以至于位于咽后间隙，导致食管和气管狭窄。
