    INPUT: Frontal and lateral views of the chest were obtained . Projecting over the right lung base , there is a 0 .8 cm partially seen nodular opacity which most likely represents nipple shadow , which can be confirmed with repeat with nipple markers . No focal consolidation , pleural effusion , or evidence of pneumothorax is seen . No definite rib fracture is seen ; however , if clinical concern for rib fracture persists , suggest dedicated rib series .
    OUTPUT:
    
Right base nodular opacity may represent nipple shadow which can be confirmed with repeat with nipple markers . Otherwise , no evidence of acute intrathoracic process . No definite rib fracture seen . However , if clinical concern for rib fracture persists , recommend dedicated rib series , which is more sensitive .
