Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Midline tracheostomy tube is again seen . The previously seen right - sided PICC is no longer present . Moderate right and a small left pleural effusions are grossly stable in position . Rounded density measuring approximately 1 .9 cm projecting over the lateral right upper lung is stable . In the interval since the prior study , there has been significant interval increase in left perihilar opacity and is some right perihilar opacity to lesser extent . Given history of pulmonary hemorrhage , findings could represent worsening hemorrhage , asymmetric pulmonary edema , infectious process not excluded . No evidence of pneumothorax is seen . The cardiac and mediastinal silhouettes are stable .
    OUTPUT:
    
Again seen bilateral pleural effusions . In the interval since the prior study , there has been significant interval increase in left perihilar opacity and is some right perihilar opacity to lesser extent . Given history of pulmonary hemorrhage , findings could represent worsening hemorrhage , asymmetric pulmonary edema , in the appropriate clinical setting , infectious process not excluded No definite evidence of cavitation is seen , although this could be better evaluated for on CT .
