21 yo female with dysphagia. Barium swallow shows circumferential radiolucent ring in upper esophagus. Proximal dilatation and jet phenomenon (Barium spurting through the ring on fluoroscopy) indicate partial obstruction.

Esophageal web:
A thin ring-like mucosal constriction projecting into the lumen
10% incidence at autopsy
Can be congenital or acquired
Most in hypopharynx and proximal esophagus
Majority protrude from anterior esophageal wall
Symptoms if lumen > 50% compromised

Sideropenic dysphagia (Plummer-Vinson syndrome)
-Iron deficiency anemia
-Esophageal web with dysphagia
-Increased incidence of carcinoma

If symptomatic, balloon dilatation; bougienage during esophagoscopy.
