Tuberculous mediastinal lymphadenopathy in adults

Abstract

Three cases of paratracheal and hilar lymph node enlargement without parenchymal lung lesion simulating sarcoidosis, lymphoma, and metastasis were finally proved to be tuberculous lymphadenitis. Although it is not a common manifestation of tuberculous infection in the adult, this possibility should be considered in the differential diagnosis of mediastinal lymphadenopathy, especially in non-whites.
