    INPUT: Single portable view of the chest is compared to prior outside reference CT scan performed earlier the same day . Left chest wall port is seen with catheter tip in the region of the mid SVC . Right - sided chest tube catheter tip at the right upper thorax . Pneumothorax is not clearly delineated on this portable exam , potentially due to projection . Surgical chain sutures project over the right upper lung . There is associated volume loss in the right hemithorax presumably from prior right upper lobectomy . The left lung is clear . Cardiomediastinal silhouette is grossly unremarkable . Right chest wall subcutaneous emphysema is again noted . Right lateral sixth rib fracture is again noted as on prior CT . Osseous structures are otherwise unremarkable .
    OUTPUT:
    
1 . Pneumothorax not clearly delineated on the current exam , although it may not be seen due to positioning . Right - sided catheter projects over the right upper chest . 2 . Right lateral sixth rib fracture , which appears recent . 3 . Postoperative changes of right upper lobectomy .
