    INPUT: Single frontal view of the chest demonstrates a large right apical bulla , compatible with findings on recent prior CT of the cervical spine . Relative left apical lucency is consistent with known paraseptal emphysema . The heart is not enlarged . Mild prominence of interstital markings could be secondary to crowding by bulla or could reflect an element of intertitial parenchymal change . Relative opacity in left mid - and lower zones may reflect atelectasis and accentuation by oblique positioning .
    OUTPUT:
    
1 . Large right apical bulla . No pneumothorax . 2 . Pulmonary findings , as decsribed above .
