Presentation
Dysphagia
Patient Data
Right paravertebral region elongated opacity that produce mass effect on the posterior wall of the trachea seen on the lateral projection.
Huge dilatation of the esophagus, with tapering at the gastro-esophageal junction representing the bird beak sign. No shouldering or obstructing lesion is seen.
Heterogenous and dependent contents seen in a dilated esophagus that produce mass effect on the heart and tracheobronchial tree.
Case Discussion
Achalasia is characterized by absent peristalsis of the esophagus and incomplete relaxation of the lower esophageal sphincter, resulting in marked dilatation and poor esophageal emptying.
