Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right - sided pigtail catheter in similar position . Interval worsening of the asymmetric right upper lobe opacity . The moderate right - sided pleural effusion has not significantly changed . There is a small apical right pneumothorax , also stable mm . Mild pulmonary vascular congestion is suspected . A moderate cardiomegaly .
    OUTPUT:
    
Interval worsening asymmetric right upper lobe airspace opacity can be worsening edema versus infection . Moderate right - sided pleural effusion and small apical pneumothorax are stable . There has been no change in the position of the right pigtail pleural drain which projects over the right mid chest . Consideration should be given to the possibility that the tube is fissural , particularly if the tube is malfunctioning .
