Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Residual right lung is better inflated following right upper lobectomy and the persistent apical pleural space is smaller and now nearly filled with fluid , overall a normal postoperative appearance . The arteries in both hila are mildly engorged and the heart though top normal size is larger compared with ___ . New generalized interstitial abnormality is mild to moderate pulmonary edema . Greater opacification in the right lower lobe is probably a combination of dependent , asymmetric edema and atelectasis , but should be monitored after the patient 's hemodynamic status improves to exclude concurrent pneumonia .
    OUTPUT:
    
1 . Small - moderate right apical hydropneumothorax . 2 . Moderate cardiomegaly , mild - moderate interstitial pulmonary edema , and moderate right pleural effusion . Superimposed right lower lobe pneumonia is not excluded .
