Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . There is subtle opacity projecting over the left upper - to - mid lung at the level of the posterior left seventh rib , unclear whether artifactual or pulmonary or possibly due to external artifact . Correlate with any external artifact at this location . If none , consider oblique views or followup chest CT . The cardiac silhouette is mildly enlarged and likely in part distorted due to patient 's thoracolumbar scoliosis . The aorta is tortuous and calcified with mediastinal contours relatively stable . No pleural effusion is seen . There is no evidence of pneumothorax . The bones are diffusely osteopenic , and again there is deformity of the proximal - to - mid right humerus , longstanding . There has been interval removal of a left - sided PICC . There are multiple chronic right - sided rib deformities .
    OUTPUT:
    
1 . Severe thoracolumbar scoliosis . 2 . Subtle opacity projecting over the left mid lung as above , may be artifactual due to external artifact , correlate with external artifact at this location . If none , suggest oblique views or non-urgent chest CT to assess for underlying lesion .
