Bilateral hilar lymphadenopathy. No lung infiltrations are shown. No fibrosis.

The plain film demonstrates stage 1 sarcoidosis (i.e. bilateral hilar lymphadenopathy).

Case Discussion

Plain chest x-ray can show four different stages of sarcoidosis:

  • stage 1: bilateral hilar lymphadenopathy
  • stage 2: bihilar lymphadenopathy and reticulonodular infiltrates of parts or the entire lung
  • stage 3: bilateral pulmonary infiltrates without signs of hilar lymphadenopathy
  • stage 4: fibrotic degeneration of the lung (possibly with upward hilar traction, cystic and/or bullous destruction of the lung)
