Dysphagia and Weight Loss


BACKGROUND

A 68-year-old, previously healthy white man presents to his primary care physician’s office with a complaint of 2 years of progressive dysphagia. He reports that he has lost about 15-20 lb and that he is not following any diet or regimen to lose weight. Although he can drink liquids without difficulty, he has lately felt a “sticky sensation” in the middle of his throat when he eats any solid food. He also regurgitates food particles from a particular meal for up to 2 days after he has eaten it. On physical examination, the patient’s vital signs are within the normal range. The examination of the oropharynx yields unremarkable findings. The patient has no neck mass or other abnormality. Examination of the thorax and the abdomen also yield unremarkable results.
A barium-swallow study is performed. Two images from this study are shown (see Images 1-2).

What is the diagnosis?

HINT
