Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lungs are clear of focal consolidations worrisome for pneumonia . There is , however , asymmetric pleural thickening at the left lung apex . This is adjacent to a healed rib and clavicular fracture and likely related to prior trauma . Cardiac silhouette is mildly enlarged . The aorta is slightly tortuous . There is no pleural effusion , pneumothorax or pulmonary edema .
    OUTPUT:
    
1 ) No evidence of acute cardiopulmonary process . 2 ) Asymteric pleural thickening at the left apex which is likely related to prior trauma given adjacent healed rib and clavicular fracture . However , if there is concern for a paraneoplastic process causing SIAD , this should be evaluated with chest CT .
