Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Diffuse increased attenuation of the lungs is partially secondary to soft tissue attenuation . Compared to the portable chest radiograph from ___ , there has been interval development of mild pulmonary edema . The tip of a right PICC is indistinct , though no lower than the mid SVC . Moderate - to - severe cardiomegaly is unchanged . There is increased opacification of the left lung base as compared to prior exam from ___ which could reflect worsening atelectasis , or possibly pneumonia or aspiration . No pneumothorax is evident . Bilateral pleural effusions are possible but difficult to assess given diffuse basilar densities .
    OUTPUT:
    
1 . Recurrence of mild pulmonary edema with possible bilateral pleural effusions . 2 . Increased retrocardiac density possible worsening atelectasis though pneumonia aspiration should be considered .
