Combined diagnostic imaging of upper gastrointestinal tract in a patient with dysphagia and suspected gastroesophageal reflux disease (GERD).

The case of a patient with intermittent dysphagia and suspected GERD is discussed. Pharyngoesophageal scintigraphy was performed. Reflux test was negative. To better define the lesion and establish the diagnosis the study was completed with an X-ray of the upper digestive tract. The finding of a barium collection and a tear in the posterior wall of the pharyngoesophageal tract was suggestive of the diagnosis of Zenker's pseudodiverticulum.
