    INPUT: A moderate - sized left pleural effusion has partially reaccumulated following recent thoracentesis procedure . Cardiac silhouette is upper limits of normal in size and accompanied by pulmonary vascular congestion and peribronchial cuffing . Additionally , a widespread reticular and nodular pattern has developed diffusely as well as more confluent opacities in the left mid and lower lung regions .
    OUTPUT:
    
1 . Partial reaccumulation of left pleural effusion , now moderate in size . 2 . Diffuse reticulonodular opacities , possibly due to pulmonary edema , but atypical or opportunistic infection is an additional consideration given the nodular appearance . If persistent after diuresis , consider a CT scan for further characterization to exclude a miliary nodular infection . 3 . Patchy and linear opacities in left mid and lower lung may be due to atelectasis or infectious consolidation .
