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

Cevap

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.

Adım Adım Çözüm

1
Recall the primary mechanism and imaging finding for Achalasia.
Failure of lower esophageal sphincter relaxation results in a "bird's beak" tapering.
This is a direct application of classic illness scripts for esophageal disorders.
2
Recall the primary mechanism and imaging finding for Diffuse esophageal spasm.
Uncoordinated contractions create a "corkscrew" appearance.
Simultaneous contractions segment the barium column on fluoroscopy.
3
Recall the classic endoscopic finding for Eosinophilic esophagitis.
Mucosal remodeling leading to "trachealization" or corrugated rings.
Chronic allergic inflammation leads to structural changes in the esophageal mucosa.
4
Recall the anatomic location and definition of Zenker diverticulum.
A posterior mucosal outpouching through Killian triangle.
This false diverticulum forms due to elevated intraluminal pressures above the upper esophageal sphincter.
