Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Mild cardiac enlargement with a left ventricular configuration appears unchanged . A curvilinear density suggesting a calcification along the left lateral margin of the heart is also unchanged . Possibly this reflects prior infarction or even an aneurysm as mentioned previously although there is no bulging contour or significant radiographic change . The aorta is again mildly tortuous . The mediastinal and hilar contours appear unchanged . There is no pleural effusion or pneumothorax . The lungs appear clear . Osteophytes along the lower thoracic spine are unchanged .
    OUTPUT:
    
No evidence of acute disease .
