[The role of episacroiliac lipomas as a cause of pseudolumbago-sciatica syndromes].

With their research, the authors intend to recall the existence of episacroiliac lipomas. These growths are important in as much as they cause low lumbar pain where the objective and instrumental signs typical of radicular lumbar syndromes are not present. Amongst other routine instrumental tests the echo scan is suggested for a more precise record. A simple operation relieves pain once and for all.
