Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . Assessment of the chest is limited by patient rotation and the patient 's chin obscuring assessment of the left apex . Heart size appears mildly enlarged but similar . The aorta is mildly tortuous . The mediastinal and hilar contours are grossly unchanged . Crowding of bronchovascular structures is present without overt pulmonary edema . Patchy opacities in the lung bases may reflect areas of atelectasis . No focal consolidation or pleural effusion is seen . There is no right - sided pneumothorax with assessment for a left apical pneumothorax being limited . No acute osseous abnormality is visualized .
    OUTPUT:
    
Limited study due to rotation and obscuration of the left apex . Low lung volumes with bibasilar patchy opacities , likely atelectasis , but infection is not excluded in the correct clinical setting .
