Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Two frontal views of the chest were provided . There is a spinal scoliosis with apparent rib cage deformity which appears unchanged . The lung volumes are low , with subtle reticular nodular opacities in the lower lungs which likely represent crowding of bronchial vasculature in the setting of low lung volumes . Please note mild pulmonary vascular congestion would be difficult to exclude . No large effusion is seen , though the left CP angle is excluded . Cardiomediastinal silhouette appears grossly unchanged .
    OUTPUT:
    
Subtle lower lung reticular nodular opacities which could represent bronchovascular crowding / atelectasis , much less likely pneumonia .
