    INPUT: Heart size is normal with a left ventricular predominance . The mediastinal contour is unchanged with widening of the superior mediastinum due to a combination of the patient 's known right lower paraitracheal / suprahilar mass and lipomatosis as seen on the prior PET - CT . Fullness of the right hilum is compatible with hilar adenopathy . Pulmonary vasculature is normal . No focal consolidation , pleural effusion or pneumothorax is identified . No acute osseous abnormalities seen .
    OUTPUT:
