Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a substantial moderate cardiomegaly with a globular configuration , which appears increased since the prior examination . Indistinct prominent perihilar opacities suggest mild - to - moderate pulmonary edema . There is no definite pleural effusion or pneumothorax . In addition to other opacities , there is an infrahilar opacity on the lateral view that appears more prominent and may correspond to obscuring of the right cardiophrenic sulcus on this examination . Incidental note is again made of an azygos fissure , which is consistent with a normal variant . The osseous structures are unremarkable .
    OUTPUT:
    
1 . Moderate cardiomegaly including substantial increase . Clinical correlation is suggested . True cardiac enlargement is a consideration , but the possibility of a pericardial effusion could also be considered clinically . 2 . Mild - to - moderate pulmonary edema . 3 . Focal infrahilar opacity , of uncertain significance . It may reflect focal edema , but a separate process such as developing focal opacity such as pneumonia or atelectasis is an additional consideration . Short - term follow - up radiographs are suggested to evaluate further .
