Abstract
Fine transverse folds can be seen by double contrast technique in the human esophagus which are similar to those seen regularly in the feline esophagus. These folds are transient in nature and possibly represent contraction of the muscularis mucosae. This fold pattern can be seen in patients with gastroesophageal reflux and in those with no symptoms of esophageal disease. The marginal serration should not be mistaken for diffuse ulceration on Ba filled views of the esophagus. Distortion or interruption of the normal fold pattern can be seen in patients with superficial ulceration due to reflux esophagitis or other invasive mucosal lesions. Although the pathophysiologic significance of this phenomenon is uncertain, demonstration and recognition of these folds allows for better definition of mucosal surface abnormalities.
