    INPUT: There is mild dextroscoliosis centered in the mid thoracic spine as well as severe degenerative changes of both shoulders , which is not significantly changed from prior and compatible with neuropathic joints in the setting of known neuromyelitis secondary to SLE . Post - thoracotomy changes are also noted in the right . Otherwise , the lungs are well expanded and clear . Cardiomediastinal and hilar contours are unremarkable . There is no cardiomegaly . No pleural effusion or pneumothorax is identified . Small oblong opacity in the left lower lung field projecting over a posterior rib likely relates to bony callus from prior fractures , better assessed in previous CT .
    OUTPUT:
    
No evidence of acute cardiopulmonary process . Small oblong opacity in the left lower lung field projecting over a posterior rib likely relates to bony callus from prior fractures , better assessed in previous CT . Findings could be confirmed with oblique views .
