    INPUT: PA and lateral views of the chest . There is no focal consolidation , vascular congestion or pneumothorax . Hazy opacity over the left lower lung laterally . In addition , there is a somewhat 1 .9 cm more focal rounded opacity over the left lower lung on the frontal view only , that was not seen on prior chest radiographs or recent chest CT . The cardiomediastinal and hilar contours are normal . Old right rib fractures noted .
    OUTPUT:
    
Nodular opacity projecting over the left lower lung measuring 1 .9 cm that was not seen on prior chest radiographs or recent chest CT . This may represent a loculated pleural fluid given recent pleural effusions and hazy opacity over the left lower lung laterally , however , pulmonary nodule can not be ruled out . Oblique views or non-emergent CT can be done to further evaluate this area .
