title: Acquired Pharyngeal Diverticulum after Anterior Cervical Fusion Operation Misdiagnosed as Typical Zenker Diverticulum.
abstract: A pharyngeal diverticulum is a rare complication of an anterior cervical discectomy and fusion (ACDF). We present a case of a pharyngeal diverticulum after an ACDF, which was misdiagnosed as a typical Zenker diverticulum. A 54-year-old woman presented with dysphagia and a sense of irritation in the neck following C5 through C7 cervical fusion 3 years prior. The patient underwent open surgery to resect the diverticulum with concurrent cricopharyngeal myotomy. An ACDF-related diverticulum is difficult to distinguish from a typical Zenker diverticulum.
