A 65-year-old woman, affected by Type II diabetes mellitus with no history of cardiac illness, referred to our hospital with a suspected diagnosis of “angina pectoris” for a cardiovascular evaluation. The patient's physical examination was unremarkable and cardiac laboratory tests, electrocardiogram and transthoracic echocardiogram were also normal. A standard chest X-ray revealed an ambiguous cor bovinum-like mediastinal image constituted of dilated thoracic esophagus profile (Fig. 1). At upper gastrointestinal endoscopy any malignancies were ruled out and in-esophagus food stagnation with difficult crossing through the esophagogastric junction was assessed.
