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 obtained five hours earlier during the same day . A right - sided pigtail and drainage tube has been placed through the right lower lateral chest wall and terminates in right - sided supradiaphragmatic position . Observe that the line appears kinked a few centimeters proximal to the pigtail end . This finding could indicate obstruction of the line . Comparison with the next previous study , the absence of any drainage line , the at that time existing massive right - sided pleural effusion has cleared up almost completely . Evidence of left - sided pleural effusion has increased in comparison with the next previous study . Quantitation of fluid , however , appears uncertain as more or less increased patient 's tilt vary position of fluid . The patient remains intubated , the ETT terminating in the trachea 3 cm above the level of the carina . No pneumothorax is seen . The position of the left - sided internal jugular approach central venous line is unchanged and terminates in the mid portion of the SVC at the level of the carina .
    OUTPUT:
    
Right - sided pigtail drainage catheter placed in lower pleura with apparently effective drainage . Unusual appearance of pigtail catheter raises suspicion for mechanical obstruction related to kink . Clinical correlation recommended . Referring physician , ___ was paged at 5 :25 p .m .
