A 58-year-old asymptomatic man with a history of gout presented for a routine physical examination. He was obese (weight, 91 kg; body-mass index [the weight in kilograms divided by the square of the height in meters], 31.1) and had decreased breath sounds at the right lung base. A chest radiograph revealed mediastinal widening with increased lucency (Panel A, arrows).
Computed tomography (CT) of the thorax performed after the intravenous administration of contrast material revealed posterior collections of fat on both sides of the mediastinum, extending from the superior mediastinum to the diaphragm.
