Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable AP upright chest radiograph was provided . A Port - A - Cath resides over the right chest wall with catheter tip extending to the region of the mid SVC . An AICD is again seen over the left chest wall with lead extending into the region of the right ventricle . Subtle opacity in the medial right lung base likely reflects bronchovascular markings , though the possibility of a subtle pneumonia is difficult to exclude without a lateral view . Otherwise , the lungs are clear . No definite pleural effusion or pneumothorax is seen . The cardiomediastinal silhouette appears normal . No acute osseous abnormalities are seen . No free air below the right hemidiaphragm . Calcification adjacent to the left humeral head is unchanged from prior studies , likely reflective of chronic tendinopathy .
    OUTPUT:
    
Subtle opacity in the medial right lung base which could represent pneumonia . Consider lateral view to confirm .
