Answer B. Non caseating granulomata

Sarcoidosis is a multisystem disease of unknown cause characterized by noncaseating granulomas in many tissues and organs, but it can cause restrictive lung disease also.

Sarcoidosis is multisystem (eye and skin involvement) but the major manifestations are bilateral hilar lymphadenopathy or lung involvement or both and these can be seen on x-ray. The lymph nodes and tonsils (in one-third of cases) are affected and are enlarged and lobulated. When seen on x-ray, the bilateral hilar lymphadenopathy is referred to as “potato nodes”.
