Esophageal intramucosal<unk>  is typically diagnosed at the time of endoscopy of the esophagus. Endoscopy shows evidence of the pseudodiverticulae, which are typically numerous, appear like pits in the wall, and may be preferentially located in the upper esophagus. The mucosal lining of the esophagus may be inflamed, and this can be seen on endoscopy or on biopsy; the mucosa, however, may also be normal if esophagitis is not the cause of the<unk> . The condition must also be excluded from esophageal cancer, which may be done at the time of endoscopy, or which may require esophageal biopsy. Pseudodiverticulae may also be seen on barium swallow imaging of the esophagus. The appearance is of flask-shaped pseudodiverticulae, which may be present in the entire esophagus diffusely, or may be segmental. The pseudodiverticulae may be seen preferentially in the lower esophagus on barium swallow also. Strictures or narrowings in the esophagus may also be seen, typically in the upper esophagus. As esophageal intramucosal<unk>  is also associated with motility disturbances of the esophagus, manometry testing of esophageal pressures may provide information to assist in the diagnosis. Irregularity in the contractions of the esophagus, prominent tertiary contractions of the esophagus, or lack of esophageal contraction (aperistalsis) have all been reported on manometric testing of the esophagus.
