Foamy esophagus sign

Foamy esophagus is an appearance seen on a single contrast barium study in Candida esophagitis with associated scleroderma/achalasia (stasis).

Pathophysiologic basis of the foamy esophagus is uncertain. Stasis is a predisposing factor. Foam is produced directly by the fungal organisms that colonize the esophagus due to the production of carbon dioxide via oxidative respiration.

The foamy esophagus is characterized by multiple tiny (1-3 mm), round lucencies that are mixed with the barium suspension along the top of the barium column, producing a layer of foam.
