Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes remain increased . Heart is normal in size and the aorta is tortuous . A 2 .9 cm opacity in the right apex with associated volume loss is unchanged and attributed to scarring from previous radiation therapy . A patchy opacity at the left base is new . There is no pleural effusion or acute skeletal abnormality .
    OUTPUT:
    
New patchy left basilar opacity is suspicious for early pneumonia in the setting of acute infectious symptoms . Given the focal nature of the opacity , follow - up chest x-rays are recommended in 8 weeks after completion of therapy to ensure resolution and to exclude the possibility of a lung neoplasm mimicking an infectious process .
