4. The chest radiograph shows mild perihilar infiltration
Frontal and lateral chest radiography shows mild increased linear opacities radiating from the hila centrally, bilaterally, consistent with “perihilar infiltration.” The findings are subtle and non-specific. Occasionally increased pressure pulmonary edema can appear fairly similar, but typically peripheral interlobular septal thickening- Kerley “B” lines- are also evident in such patients. Furthermore, there may be pleural effusions and the heart size may be increased when increased pressure pulmonary edema is present, and these findings are lacking in this young patient. No consolidation is seen, nor is clear evidence of peribronchial and mediastinal lymphadenopathy.
