CTICasesBenign Esophageal Stricture
Imaging findings
Lateral chest radiograph shows anterior displacement of the trachea and widening of the retrotracheal space. CT chest shows a severely dilated esophagus containing impacted food debris, ending in a focal, benign-appearing stricture without a soft tissue mass, confirmed on endoscopy.
Key takeaways
A dilated, food-filled esophagus (megaesophagus) secondary to a stricture or achalasia can manifest on radiographs as retrotracheal opacity and tracheal deviation. Endoscopy is required to differentiate benign strictures from esophageal carcinoma.
