    INPUT: Two views were obtained of the chest .

Left midlung and multiple right - sided metastases are better assessed on the recent CT torso . The heart is normal in size with single lead defibrillator noted . Port -a - Cath terminates in the right atrium as on the CT . Blunting of the costophrenic sulci posteriorly could reflect trace pleural effusions .
