Patient case (clinical description): A 67-year-old woman comes to the clinic due to recent episode of choking, dysphagia, and cough.  Her other medical problems include hypertension, dyslipidemia, and osteoarthritis.  She does not smoke or use alcohol. She lives with her husband and she is able to do her own daily activities. She used to teach elementary school. Blood pressure is 135/80 mm Hg.  The patient's breath smells bad. Other physical examinations are normal.  A barium swallow study reveals an abnormality in the upper esophagus with an outpouching at the junction of the lower part of the throat and the upper portion of the esophagus.

Patient's own account: I'm a 67-year-old lady, and I went to the clinic due to nonstop choking, difficulty swallowing, and coughing. I also suffer from hypertension, cholesterol, and osteoarthritis. I do not smoke or drink alcohol. I live with my husband, and we are independent retired elementary school teachers. During the exam, my blood pressure was 135/80 mm Hg. The doctor told me I had a smelly breath. How embarrassing! The rest of my physical exam was normal. I did a barium swallow test, which is an X-ray of my throat, which revealed a problem in the upper part of my esophagus, where there's a small pouch or bulge at the spot where my throat meets the esophagus.
