Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a new dense right central opacity approximately 7 cm x 3 cm on frontal view . Given the rapid onset of this finding , the differential is limited to airspace consolidation ___ atelectasis . Given previous radiographic evidence of slow neo-esophageal / gastric emptying , it is possible that patient had aspirated contrast material . This would also explain the dense opacity seen on lateral projection . However , other radiopaque fluid , such as fluid , pus , ___ ___ , ___ be filling the airspace in this region . Adjacent to this dense opacity are ill - defined peripheral opacities which is not matched on the contralateral side . The left lung is unremarkable . There is no pleural effusion ___ pneumothorax . There is pronounced flattening of the hemidiaphragms . The cardiomediastinal silhouette is unchanged and within normal limits . The pleural surfaces are unremarkable .
    OUTPUT:
    
Large dense right central opacity which ___ represent collapse ___ airspace consolidation with adjacent area of asymmetric pulmonary edema . Given history of lymphadenopathy , collapse could be secondary to nodal compression of an airway . Alternatively , given recent history of oral contrast and poor gastric emptying , opacity ___ represent aspirated contrast material . Consolidation also ___ be secondary to a fistula between the neo-esophagus and the right lung . If this finding represent consolidation , the radiopaque material can not be identified definitely and ___ represent ___ , fluid ___ pus . CT imaging is highly recommended for further evaluation of this finding . These findings were discussed with Dr . ___ at 12 :45 p .m . via phone by ___ .
