A 72‐Year‐Old Man With Dyspnea, Circumferential Aortic Thickening, and Weight Loss

History of the present illness One month before admission, the patient was studied by a general practitioner as a result of a 15-kg weight loss during the previous 3 months, as well as hyporexia and asthenia. He reported occasional fever, mainly in the evenings. For this reason, tumor markers and abdominal echography were performed, without pathologic findings, and a gastroesophageal endoscopy only manifested a hiatal hernia. In addition, he experienced slow but progressive worsening of his New York Heart Association functional class during the last 2 months. He had required an emergency department admission with congestive heart failure. A bilateral pleural effusion was documented, and he was admitted under treatment with diuretics and angiotensinconverting enzyme inhibitors.
