["Transparent circles" lymph glands: an unusual appearance on lymphography in certain proliferative lymphoid...

The authors describe 27 cases in which a very particular type of lymphographic image was observed, associating disseminated lesions in all the retroperitoneal lymph glands, and an appearance of "circled" glands of very weak density. This image may be rarely observed in Hodgkin's disease and non-Hodgkin type hematosarcomas. It is frequently observed, however, during the course of angio-immunoblastic lymphadenopathy. Whatever the etiology, this image is of particularly poor prognostic significance.
