    INPUT: Heart is upper limits of normal in size and accompanied by pulmonary vascular congestion and bilateral interstitial opacities , most pronounced in the periphery of the mid and lower lungs . Additionally , there are more confluent poorly defined opacities in the left upper and left lower lobes . The left upper lobe opacities have a nodular configuration . Small pleural effusions are present bilaterally . Lung volumes are increased suggesting underlying COPD , and there is a probable small calcified granuloma at the right apex .
    OUTPUT:
    
1 . Poorly defined consolidation in left upper and left lower lobes concerning for multifocal pneumonia . Recommend followup chest x-ray in four weeks after completion of antibiotic therapy to ensure resolution and exclude neoplasm , especially since the left upper lobe opacities have a nodular configuration . 2 . Suspected co-existing interstitial edema may also be re-assessed on followup chest radiograph . 3 . Small bilateral pleural effusions with likely component of co-existing pleural thickening on the left .
