Back pain with persistent cough and dysphagia and an apparent left ventricular hypertrophy most likely indicates which condition?

• A. Aortic dissection
• B. Thoracic aortic aneurysm
• C. Myocardial infarction
• D. Esophageal diverticulum

Answer: (B)

Thoracic aortic aneurysm is suggested when there is a mediastinal process that can press on nearby structures. A dilated thoracic aorta can squeeze the esophagus, producing dysphagia, and irritate the trachea or recurrent laryngeal nerves, causing a persistent cough. The back pain comes from the stretching and expansion of the aortic wall as the aneurysm enlarges. The combination of back pain with coughing and swallowing difficulty points to a mass effect in the posterior mediastinum from an enlarged thoracic aorta rather than a primary heart attack or a pure esophageal issue. Aortic dissection would typically present with sudden, severe, tearing chest or back pain and acute hemodynamic changes rather than a gradual back pain with dysphagia and cough. Myocardial infarction mainly causes chest pain related to myocardial ischemia and lacks the specific esophageal compression signs. An esophageal diverticulum can cause dysphagia, but it does not explain the back pain and cough together, nor the apparent LV changes. The LVH finding is likely a concurrent hypertensive state or another non-specific finding and does not explain the symptom set as well as a thoracic aortic aneurysm does.
