There are multi focal regions of opacity specifically in the bilateral perihilar region and bilateral costophrenic angles , overall worse on the right compared to the left . Blunting of the posterior costophrenic angles may be due to small superimposed pleural effusions . The cardiomediastinal silhouette is within normal limits .
