From the case:
Dense hilum sign - lung cancer
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/114308/annotated_viewer_json?lang=us"}
Large mass at the anterior aspect of the right hilum extending into the right middle and upper lobes. Distal atelectasis in the right middle lobe. Mediastinal lymphadenopathy.
Case Discussion
This patient had a subsequent diagnosis of lung cancer (histopathology unknown) and underwent radiation treatment. The dense hilum sign is one to be aware of on frontal radiographs, as a mass can easily be overlooked. In this case, however, it is readily localized on the lateral and when compared to the prior the difference in density of the right hilum is apparent.
