Match each esophageal disorder with its most characteristic diagnostic finding on imaging or endoscopy.
- Achalasia"Bird's beak" tapering of the distal esophagus
- Diffuse esophageal spasm"Corkscrew" pattern on barium swallow
- Eosinophilic esophagitisMultiple corrugated rings ("trachealization") on endoscopy
- Zenker diverticulumPosterior mucosal outpouching through Killian triangle
Answer
Achalasia matches with "Bird's beak" tapering; Diffuse esophageal spasm matches with "Corkscrew" pattern; Eosinophilic esophagitis matches with multiple corrugated rings; Zenker diverticulum matches with posterior mucosal outpouching.
Each esophageal disorder has a highly specific anatomic or functional abnormality that produces characteristic findings. Achalasia's impaired lower esophageal sphincter relaxation produces a smooth distal tapering ("bird's beak"). Diffuse esophageal spasm's uncoordinated contractions produce a "corkscrew" shape. Eosinophilic esophagitis causes chronic mucosal changes that appear as concentric rings. Zenker diverticulum is a direct structural herniation (false diverticulum) at Killian triangle.
