Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are slightly low . Cardiac silhouette appears prominent but could be exaggerated by shallow inspiration . Mediastinal and hilar contours are unremarkable . There is increased peribronchial density in the lower lobes on the lateral view . On the PA view , it is not clear whether it is more prominent on the right than left . There is no pleural effusion or pneumothorax , and no evidence for pulmonary edema . There is mild anterior wedging of ___ mid to lower thoracic vertebral bodies .
    OUTPUT:
    
1 . Prominence of peribronchial markings in the lower lobes , possibly greater on the right than left , is compatible with atypical pneumonia , given the patient 's history . 2 . Cardiac silhouette is abnormally prominent for age , but this could be secondary to shallow inspiration . Clinical correlation is suggested .
