Chest Radiographic Staging System for Sarcoidosis
What is the chest radiographic staging system for sarcoidosis, and what is the clinical significance?
Here is the table which summarizes the staging system for sarcoidosis. The higher the stage of sarcoidosis, the greater the likelihood that the patient will experience chronic respiratory deficits.
| STAGE | RADIOGRAPHIC APPEARANCE |
|---|---|
| 0 | Chest radiograph appears normal |
| I | Chest radiographic evidence of hilar or mediastinal lymphadenopathy without evidence of interstitial lung disease |
| II | Chest radiographic evidence of hilar or mediastinal lymphadenopathy and evidence of interstitial lung disease |
| III | Chest radiographic evidence of interstitial lung disease without evidence of hilar or mediastinal lymphadenopathy |
| IV | Chest radiographic evidence of interstitial fibrosis with distortion of pulmonary structures, such as blood vessels, without evidence of hilar or mediastinal lymphadenopathy |
