    INPUT: Frontal and lateral views of the chest were obtained . Lungs are clear without focal consolidation . No pleural effusion or pneumothorax is seen . There is minimal left apical pleural thickening again seen . Cardiac and mediastinal silhouettes are stable and unremarkable .

No acute cardiopulmonary process . Please note that the questionable focus of opacity projecting over the right anterior second rib is no longer present and thus likely artifactual on the prior study .
