Transition from nutcracker esophagus to achalasia. A case report.
We report a middle-aged woman with nutcracker esophagus who progressed to classic achalasia in two years. Several previous reports have documented progression of nutcracker esophagus to diffuse esophageal spasm and diffuse esophageal spasm to achalasia, but the only previous report of nutcracker esophagus progressing to achalasia was in a child. Our case suggests that, in some instances, nutcracker esophagus and achalasia may share the same pathogenesis.
