Pharyngeal pseudodiverticulum in an adult.

Posterior perforation of the cervical portion of the esophagus may present deceptive clinical and roentgenographic pictures. In the neonate, the clinical picture resembles that of esophageal atresia; in the adult, the roentgenographic appearance may resemble Zenker diverticulum. In either instance, treatment should be no different from that employed for more commonplace esophageal perforations, namely, prompt, aggressive surgical intervention.
