Fig. 3. —74-year-old woman with diffuse esophageal spasm who presented
with dysphagia. Prone right anterior oblique view from single-contrast
esophagram shows nearly lumen-obliterating nonperistaltic contractions
(straight white arrows) with tapered, beaklike narrowing (black
arrow) of distal esophagus near gastroesophageal junction secondary to
incomplete opening of lower esophageal sphincter. Hiatal hernia (curved
white arrow) is also visible.
