Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear unchanged . Coarsened appearance of lung markings is more prominent than on the prior radiographs , particularly in the right lung , but there is no focal consolidation , only patchy left basilar opacity obscuring the left costophrenic sulcus , suggestive of minor atelectasis . It is also difficult to exclude a tiny pleural effusion on the left . Mild rightward convex curvature is again centered along the mid thoracic spine .
    OUTPUT:
    
Increased interstitial prominence , particularly in the right lung , since the prior study . Airway inflammation or atypical infection could be considered in the appropriate clinical setting , although the appearance is not specific . No focal consolidation .
