Mediastinal Lipomatosis in Simple obesity*

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