title: Isolated symmetrical mediastinal lipomatosis.
abstract: Symmetrical mediatinal lipomatosis is a rare benign condition characterized by deposition of a large amount of mature adipose tissue within the mediastinum. Usually secondary to exogenous obesity, administration of steroids and Cushing's disease, it is more common in middle-aged males and is associated with alcohol abuse. Various other associations have been reported. CT and MRI can decisively diagnose this benign condition, which also helps in deciding treatment options. We present a case of a young female with a bizarre appearance on chest radiographs. Isolated, bilaterally symmetrical mediastinal lipomatosis was diagnosed on CT and MRI. The patient was thin and did not consume alcohol or steroids. Cushing's disease and other known associations were excluded.
