[Radiological diagnosis of tumoral lipomatosis of the renal sinus. The role of arteriography (author's transl)].

In twenty cases of pseudo-tumoral sinusal lipomatosis for which the patients had undergone renal arteriography, the authors investigated the urographical and arteriographical clinical signs by comparing them with the previously published data. After reviewing these various elements and considering the various possible diagnoses, they came to the conclusion that, although the arteriographic signs are quite distinctive, they are not absolutely essential for diagnosis of this disorder--which it should be possible to confirm unreservedly from the urographical data in all cases in which there are considerable anatomical lesions. A well-managed urographical technique and careful assessment of the facts should allow arteriography to be discarded, indications for this only being justified where there is an associated symptomatology, especially haematuria.
