Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear unchanged . There is no pleural effusion or pneumothorax . Although there is no definite focal opacity to suggest pneumonia or vascular abnormality to suggest pulmonary edema , there are , at both the apices and along each costophrenic sulcus , vague increased interstitial opacities . This indicates the possibility for developing interstitial lung disease . Bony structures are unremarkable . No fracture is identified .
    OUTPUT:
    
Findings which may suggest developing interstitial lung disease . If further assessment is desired , then dedicated chest CT could be considered in followup .
