Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are increased opacities in the lung bases , left greater than right . Findings likely reflect recurrence of bilateral pleural effusions . Underlying consolidation may be due to atelectasis , though aspiration or pneumonia , particularly in the left lung base , can not be excluded . Mild vascular congestion is evident , however , there is no overt pulmonary edema . Detailed evaluation of the hilum and cardiac contours is limited due to basilar opacities , but there is marked cardiomegaly . There is no pneumothorax . A right PICC line terminates in the mid SVC .
    OUTPUT:
    
Recurrence of bilateral pleural effusions , moderate on the left and small on the right . Probable associated underlying bibasilar atelectasis , though pneumonia or aspiration , particularly within the left base , can not be entirely excluded . Vascular congestion present .
