Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is no focal consolidation , effusion , or pneumothorax . There is asymmetric opacity projecting over the left first costochondral junction with respect to the right . On the lateral view , there is also increased opacity projecting over the anterior superior endplate of an upper thoracic vertebral body which could correlate with a finding on the frontal view . Cardiomediastinal silhouette is within normal limits . No acute osseous abnormalities .
    OUTPUT:
    
No acute cardiopulmonary process . Asymmetric opacity projecting over left first costochondral junction . This could entirely be degenerative however given possible correlative finding on the lateral view projecting over the lungs , apical lordotic view is suggested to further localize finding to the osseous structures or underlying lung .
