[The dynamics of the diseases of hilar and mediastinal lymph nodes as seen by fluorography (author's transl)].

Fluorographic anamnesis of patients with sarcoidosis and lymphogranulomatosis was studied. The fluorograms carried out prior to the discovery of diagnosis of sarcoidosis were found normal in 21 out of 25 cases, they showed signs of pathologic changes in 4 patients. On the other hand, in patients with Hodgkins disease the preliminary fluorogram was normal in 13 cases, abnormal in 13 patients. Differences were found in the form of radiologic picture as well: sarcoidosis caused symmetrical enlargement of the hilar lymph nodes, in lymphogranulomatosis enlargement of the paratracheal ones could be observed.
