    INPUT: Heart size is mildly enlarged . The aorta remains tortuous . Calcified bilateral hilar mediastinal lymph nodes are re - demonstrated compatible prior granulomatous disease . Pulmonary vasculature is not engorged . Bibasilar linear and patchy opacities may reflect areas of atelectasis . Chain sutures are noted in the right lung base compatible prior wedge resection . There is marked gaseous distention of colonic loops of bowel within the left upper quadrant resulting in left diaphragmatic elevation and atelectasis in the left lung base no pneumothorax is present . There are no acute osseous abnormalities detected .
    OUTPUT:
    
Bibasilar patchy and linear opacities , potentially atelectasis , but aspiration or infection can not be excluded . Left diaphragmatic elevation due to marked gaseous distention of colonic loops of bowel in the left upper quadrant of the abdomen . Clinical correlation with abdominal examination is recommended , and consider further assessment with abdominal radiograph or CT of the abdomen if necessary .
