title: Mediastinal lipomatosis in simple obesity.
abstract: A case of superior mediastinal widening due to unusual amounts of fat accumulations is reported in a patient with simple obesity, not associated with iatrogenic or primary Cushing's syndrome. The radiographic features included a smooth bilateral widening of the superior mediastinum, relative lucency, no definable mass in the lateral view, and no pressure effects on the trachea. Such mediastinal lipomatosis is a benign condition and may be related to general obesity. although rare, it should be considered in the differential diagnosis of mediastinal masses, particularly in obese individuals.
