Treatment was carried out obtaining favorable evolution; Five days later, the patient returned with symptoms of recurrent vomiting, polyphagia and polydipsia, cough and dysphagia. After physical inspection, abnormal undulating movements are evident in the cervical esophagus, digital radiography with contrast medium (Barium Sulfate) is performed, showing an increase in the size of the esophagus in its cervical and thoracic portion compatible with megaesophagus.
