Systemic lupus erythematosus: an unusual cause of bilateral hilar lymphadenopathy

Systemic lupus erythematosus is usually not associated with bilateral hilar adenopathy. We report a young woman with arthralgias, fever, pleuritic pain, peripheral and hilar lymphadenopathy, high titer ANA, and a low serum complement. Transbronchial lung biopsy revealed interstitial pneumonitis. SLE should be considered an unusual cause of hilar adenopathy.
