Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral chest radiographs demonstrate severe cardiac enlargement which may be underestimated due to PA technique when compared to prior AP radiograph ( which normally exaggerates cardiac silhouette slightly ) . Mediastinal and hilar contours are unchanged . Lung parenchyma demonstrates prominence of the interstitium in conjunction with mild bronchial wall cuffing , likely reflecting chronic underlying disease though element of mild edema is a consideration . An 11 mm nodular opacification in the left upper lung , correlating with FDG - avid lesion , is better assessed on recent chest CT . No pleural effusions or pneumothorax evident . Multiple stable mild lower thoracic compression deformities present . Sternotomy sutures are midline and intact .
    OUTPUT:
    
Mild prominence of the interstitium in setting of cardiomegaly reflects mild fluid overload . 11 mm left upper lobe opacity corresponds with known mass . No pleural effusions .
