Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette remains enlarged with upper zone vascular redistribution , peribronchial cuffing , and overall worsening of diffuse reticular and nodular opacities bilaterally . Additionally , there are a few larger poorly defined nodular opacities in the mid and lower lungs which appear slightly more pronounced than on the prior study . There are no segmental or lobar areas of confluent consolidation . Small bilateral pleural effusions are present , with some extension of fluid into the fissures . Unchanged compression deformity in the lower thoracic spine .
    OUTPUT:
    
Overall worsening of interstitial pattern , likely due to atypical pneumonia , although coexisting hydrostatic edema is possible in the setting of cardiomegaly and pulmonary vascular redistribution .
