Paracardiac lipomatosis in exogenous Cushing's syndrome.

, , 653-656. Histologically proven lipomatosis presenting as paracardiac masses on the chest radiograph is described in a patient with a renal graft. This lesion was caused by the prednisone therapy and diminished after lowering the dosage. Review of 90 renal transplant patients revealed one likely example of this syndrome and four patients had other radiographic abnormalities suggestive of intrathoracic lipomatosis. It is pointed out that intrathoracic lipomatosis can produce a variety of abnormalities on the chest radiograph and that sometimes these changes need to be differentiated from primary tumours.
