title: [The Löfgren syndrome: acute sarcoidosis (author's transl)].
abstract: Report on 3 cases of acute sarcoidosis, the Löfgren syndrome. 3 signs: skin changes like erythema nodosum, widening of the hilus due to enlarged lymphglands and arthralgias. Diagnostically this has to be separated from maligant systemic disease and deserves, therefore, the special interest of the radiologist.
