    INPUT: PA and lateral views of the chest . There is vague opacity projecting over the right lung apex . In addition , there is thickening along the right pleura at the anterior junction line . Overall this is suggestive of pleural - based disease . Elsewhere , the lungs are clear without focal consolidation or effusion . Cardiomediastinal silhouette is within normal limits . Osseous and soft tissue structures are grossly unremarkable without visualized displaced rib fracture .
    OUTPUT:
    
Vague opacity projecting over the right upper lung , likely pleural - based , for which CT scan should be performed unless old films become available to document stability .
