Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is normal . The aorta remains mildly tortuous . Mediastinal contours are otherwise unremarkable . Hyperinflation of the lungs with relative attenuation of the pulmonary vascular markings towards the apices is compatible with emphysema . Rounded ill - defined opacity within the periphery of the right upper lobe measuring up to 3 .9 cm may reflect the patient 's known malignancy . Patchy ill - defined opacification within the right lung , particularly of the right lung base , could reflect infection . Scattered calcified granulomas are noted in the periphery of the left lower lobe . Hilar contours are otherwise relatively unchanged . There is no pneumothorax . Mild right apical and lateral pleural thickening or fluid is noted . No left - sided pleural effusion is identified . There are no acute osseous abnormalities .
    OUTPUT:
    
Patchy ill - defined opacity within the right lung , more so in the right lung base , could reflect infection . Rounded opacity within the periphery of the right upper lobe may reflect the patient 's known malignancy , and comparison with recent previous imaging is recommended . Right apical and lateral pleural thickening or fluid .
