Table 1

Staging of pulmonary sarcoidosis based on chest X-ray.

Staging	Description
0	Absence of chest X-ray abnormalities
1	Bilateral hilar lymphadenopathy that may be accompanied by right paratracheal and aortopulmonary window adenopathy
2	Bilateral hilar lymphadenopathy and parenchymal infiltration with a bilateral symmetric micronodular or reticulonodular pattern with predominant perihilar distribution, in middle and upper lung fields
3	Parenchymal infiltration without hilar adenopathy
4	Fibrosis with evidence of reticular pattern with traction bronchiectasis, masses causing architectural distortions, or honeycomb cysts, predominantly in the upper fields
