Abstract
A 78-year-old man with amyloidosis involving the esophagus is described. The clinical and radiographic features resembled classic achalasia, while esophageal manometrics demonstrated aperistalsis, incomplete LES relaxation, but a normal LES resting pressure. A review of the literature suggests that esophageal amyloid may have variable presentations. This patient was successfully managed with forceful pneumatic bag dilatation.
