[Angiolipoma of the kidney (clinical course and radiodiagnosis)]

The clinico-echographic data on 91 cases of angiomyolipoma of the kidney are presented. This pathology appears to be the most frequent renal tumor in women. It usually has no clinical signs. Echographic examination typically produces images of formations having distinct contours; image quality is basically determined by fat level. More often than not, the image densitometric characteristics are rather low. The signs of a spontaneous rupture of tumor are discussed. Angiomyolipoma grows slowly--0-5 mm within 3 years. Check-ups (chiefly, echography) should be carried out every 12 or 24 months.
