Transient fine 1-2 mm transverse circumferential folds in the distal esophagus on barium.
Updated On: Jun 23, 2026
- Esophageal atresia
- Esophageal stenosis
- Feline oesophagus
- Tracheoesophageal fistula
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: The diagnostic key on this barium swallow is the texture of the wall - delicate, closely spaced transverse ripples encircling the lumen. That fleeting corrugated look is termed the feline esophagus.
Step 2: The mechanism is a brief contraction of the longitudinally oriented muscularis mucosa, throwing up 1-2 mm circumferential folds. Because they vanish quickly, they are a transient finding rather than fixed pathology.
Step 3: Location and timing seal it: the bands sit in the distal two-thirds of the thoracic esophagus, surface after a reflux event, and are most evident when the esophagus is only partially distended. They often have no clinical significance but link to GERD.
Step 4: Distractor check - atresia/TEF are neonatal congenital lesions, and stenosis is a persistent caliber narrowing; none gives a transient herringbone fold pattern. \[\boxed{\text{Feline oesophagus}}\]
