Bilateral hilar lymphadenopathy in a young female: a case report

Hilar or mediastinal lymphadenopathy is not included in the wide spectrum of radiologic findings associated with bronchiolitis obliterans-organizing pneumonia (BOOP). We present a patient who presented with extensive hilar and mediastinal lymphadenopathy. We suspected a diagnosis of sarcoidosis. The patient was diagnosed with idiopathic BOOP. This is the first case demonstrating that BOOP, now referred to as cryptogenic organizing pneumonia (COP), can present with bilateral hilar lymphadenopathy.
