    INPUT: Heart is upper limits of normal in size with left ventricular configuration . Upper zone vascular redistribution is accompanied by peribronchial cuffing and basilar predominant septal lines , with similar pattern to previous episodes of reported interstitial edema on earlier chest radiographs . Note is also made of a more focal poorly defined opacity in the right infrahilar region , corresponding to the middle lobe on the lateral view . Calcified left upper lobe granuloma is unchanged . There is no pleural effusion or acute skeletal abnormality . .
