• Massive dilatation of the esophagus with air fluid level
• Barium studies with increased pressure, in upright position, a small amount of barium spurts into the stomach giving rise to "Bird Beak appearance"
• Aspiration - infiltrative changes  both lungs
• Higher incidence of esophageal carcinoma
