Zenker's diverticulum in an 85-year-old Ugandan man.

Background: Zenker's diverticulum (ZD) is an uncommon disorder due to an outpouching of tissue through the Killian triangle that is thought to be caused by dysfunction of the cricopharyngeal muscle.
Case Presentation: An 85-year-old male patient presented with odynophagia and dysphagia of initially solid food followed by fluids that was associated with a significant weight loss over a one-year period. Barium swallow videofluoroscopy demonstrated a posterior outpouching of proximal esophagus that was 2 cm from the epiglottis. With the diagnosis of medium sized ZD, the patient underwent endoscopy guided diverticulotomy. Six months after the procedure, he was asymptomatic and had gained weight.
Conclusions: Dysphagia and weight loss raises a clinical suspicion for a malignancy. Barium swallow examination is an inexpensive method for the diagnosis of ZD.
