Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP single view of the chest has been obtained with patient in semi-upright position . Comparison is made with the next preceding similar study of ___ . Again , patient is rotated to the right . Asymmetric appearance of the frontal chest view is accentuated by previously described orthopedic hardware and vertebral body placement in the lower thoracic spine with moderate degree of general right - sided convex scoliosis . The heart size has not changed since the preceding examination . There is no evidence for pulmonary vascular congestion in the right hemithorax where the pulmonary vasculature can be identified . A new diffuse haze is overlying the entire left - sided hemithorax . As the patient is in steep dorsal tilt position , the haze can be explained by pleural effusion that is layering in the posterior pleural compartments . There is no pneumothorax seen on either side . A previously described right - sided Port - A - Cath system with entrance via the right internal jugular vein remains in unchanged position . A previously existing left internal jugular approach central venous line has been withdrawn .
    OUTPUT:
    
Left - sided diffuse haze over hemithorax is likely representing layering left - sided pleural effusion . No evidence of pulmonary vascular congestion can be seen on portable chest examination . A lateral chest view would confirm present made observations as relating to pleural effusions . Referring physician , ___ , was paged at 1 :30 p .m .
