Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Diffuse bilateral airspace opacities worse in the left midlung are extensive . A nodular opacity at the left lung base is concerning for a pulmonary nodule . There is mild cardiomegaly . A cardiac conduction device is contiguous with leads which end in the right ventricle , through the coronary sinus and probably right atrium . A right PICC ends in the mid SVC . An endotracheal tube ends in the mid thoracic trachea . The distal tip of an enteric tube is not definitively visualized but likely courses below the level of the diaphragm .
    OUTPUT:
    
Diffuse , extensive bilateral airspace opacities are seen . A more nodular focus in the left lung base is also noted . These findings could represent multifocal pneumonia , pulmonary hemorrhage or sequelae of malignancy given the nodular opacity in the left lung base . Correlation with clinical history is recommended . If no clinical history is available CT is recommended for further evaluation .
