Zenker's diverticulum (ZD) is a type of esophageal diverticulum, a relatively rare disease in the pharyngoesophageal area. It is a pulsion diverticulum, or false diverticulum, located dorsally at the wall between the pharynx and esophagus. This area is known as Killian's triangle or dehiscence and is a region of relative weakness. Common symptoms of ZD include dysphagia, choking, persistent cough, loss of weight, hoarseness, halitosis, regurgitation of undigested food, and borborygmi within the cervical region. We are reporting a case of oropharyngeal dysphagia due to a ZD in a 65-year-old man with a history of worsening dysphagia for two years. Clinical presentation, diagnosis, and treatment options for ZD are discussed, along with the underlying pathophysiology of this condition.
