Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low exaggerating the cardiac silhouette and pulmonary vasculature . Heart size is top normal with mild tortuosity of the thoracic aorta . Hilar contours are unremarkable . There is consolidation of the right lung base with loss of the hemidiaphragmatic contour reflecting probably pleural effusion with either associated atelectasis or possible pneumonia . The upper lung fields are clear . There is no pneumothorax .
    OUTPUT:
    
Right base consolidation with loss of the hemidiaphragmatic contour which likely represents pleural effusion with either associated atelectasis or pneumonia . Investigation of the right upper quadrant with ultrasound could be a useful confirmatory tool to confirm effusion as well as for evaluation of subdiaphragmatic pathology .
