Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is increased fine reticulation within both lungs which may represent mild interstitial edema . Mild increased opacification of the right as well as the left lung base with minimal silhouetting of the left medial hemidiaphragm may represent worsening edema or atelectasis ; however , infectious process such as pneumonia can not be excluded in the correct clinical setting . Trace left - sided pleural effusion can not be completely excluded . The cardiac silhouette appears mildly prominent but not significantly changed from the most recent prior examination . Mild cephalization of pulmonary vasculature is noted .
    OUTPUT:
    
Mild cardiomegaly with increased reticulation in bilateral lungs with mild cephalization may represent mild volume overload . Opacification at bilateral lung bases may represent worsening edema versus atelectasis ; however , infectious process is doubted but may be considered in the correct clinical setting .
