    INPUT: Since the prior examination , there has been interval development of opacification within the right lower lobe , some of which demonstrate a nodular configuration . There are no pleural effusions or pneumothorax . There are no other focal areas of opacification . The cardiomediastinal and hilar contours are stable with changes relating to known esophagectomy and neoesophagus formation , and tortuosity of thoracic aorta . Pulmonary vascularity is not increased .
    OUTPUT:
    
Right lower lobe opacification with nodular component , most compatible with pneumonia . However , given relative nodularity , followup to resolution is recommended with repeat radiographs after treatment .
