Rat Tail Appearance of the GE Junction

Ashley Davidoff MD

Definition

Rat Tail of the esophagus is the characeristic of shape of the GE junction caused by spasm of the LES, aperistalsis, and consequent dilatation of the esophagus.

Air Fluid Level and Rat Tail Appearance of the LES in Achalasia

The single contrats barium swallow shows an air-fluid level is seen in the dilated esophagus. (a) The hypertonic LES has a “rat-tail” appearance as seen in image b. Intermittant opening of the LES allows a variable amount of food or fluid through into the stomach.

Achalasia with Enormous Esophagus, Bezoar and Rat Tail Esophagus

A CTscan through the chest shows a huge esophagus filled with solid food. (a,b) A bezoar is included in the differential diagnosis. In d the distal esophagus has a rat-tail appearance at the zone of transition.
