Forty-eight cases of tuberculous hilar lymphadenopathy were studied. Patient's population and their clinical manifestations, especially the modes of onset of the disease were found to be different from those of the previous surveys. Age distribution of cases shifted from younger to elderly groups. Roentgenologically, the cases of typical primary complex has been declining, while the atypical patterns such as solitary mediastinal lymphadenopathy or those associated with healed pulmonary lesions have increased. Since the introduction of RFP to treatment for tuberculosis, the cases diagnosed incidentally because of early exacerbation has been increasing. Ten out of total 48 cases were presumed not being originated from the primary complex, but from reactivation. Relative increase of such cases may partly explain the recent shift of hilar lymphadenopathy to elderly group.
