    INPUT: The cardiac silhouette is moderately a markedly enlarged . The aorta is unfolded . No pleural effusion is seen . No definite focal consolidation is seen . In the left mid to lower lung retrocardiac region there is an apparent rounded opacity , measuring approximately 1 .9 x 1 .5 cm ; the differential diagnosis being pulmonary nodule versus artifact . Recommend follow - up chest CT for further assessment . Prominence of the central pulmonary vasculature suggests pulmonary vascular engorgement without overt pulmonary edema .
    OUTPUT:
    
Central pulmonary vascular engorgement without overt pulmonary edema . 1 .9 x 1 .5 cm rounded opacity in the left mid to lower hemi thorax , projecting over the cardiac shadow , differential diagnosis includes pulmonary nodule versus artifact . Recommend followup non emergent chest CT for further assessment .
