Fig. 1.4

(ac) Sarcoidosis manifesting as bilateral hilar and mediastinal lymph node enlargement. (a) Frontal chest radiograph of a 71-year-old woman with nonproductive cough shows bilateral hilar (arrows) and right paratracheal (arrowheads) lymph node enlargement. (b) Lateral radiograph confirms enlargement and increased density of the bilateral hila as well as soft tissue in the inferior hilar window (the so-called doughnut sign) consistent with bilateral hilar and mediastinal lymphadenopathy (arrows). (c) Contrast-enhanced coronal MIP at mediastinal windows at the level of the carina confirms enlarged hilar (H), bilateral paratracheal (P), and subcarinal (S) lymph nodes
