OBJECTIVE. The purpose of this study was to determine the frequency and appearance of esophageal wall thickening on CT scans in a series of patients with findings of diffuse esophageal spasm on barium studies.

CT showed significantly greater esophageal wall thickening in the lower thoracic esophagus 5 cm above the gastroesophageal junction than in the upper thoracic esophagus at the level of the aortic arch or in the midthoracic esophagus at the level of the carina (p
