    INPUT: The examination is limited secondary to patient 's inability to cooperate . The left costophrenic angle is excluded from the film . There is near - complete opacification of the right lung base , likely a combination of new pleural effusion and consolidation . Density in the retrocardiac region is less severe than the right . There is increased central pulmonary vascular congestion as compared to prior . The thoracic aorta appears tortuous . Cardiac contours remain enlarged .
    OUTPUT:
    
1 . Right lower lobe opacity , likely a combination of airspace disease ( atelectasis or pneumonia ) and effusion . 2 . Retrocardiac opacities may reflect areas of subsegmental atelectasis . 3 . Increased pulmonary vascular congestion without overt edema . 4 . Stable moderate cardiomegaly
