Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are well inflated . Patient has pectus excavatum deformity of the sternum . Again seen is increased opacity abutting the right heart border on the frontal projection which is similar to the prior exam and likely reflects normal bronchovascular markings exaggerated in the setting of a pectus excavatum deformity . However , in the correct clinical setting it is difficult to exclude a subtle pneumonia in this region . Cardiac enlargement is again noted . Mediastinal contour is normal . Hilar congestion is noted . No frank edema . No large effusions or pneumothorax . Bony structures are intact .
    OUTPUT:
    
1 . Pectus excavatum deformity of the sternum likely simulates a right middle lobe pneumonia though clinical correlation is advised . 2 . Cardiomegaly with mild hilar congestion .
