title: [Anomalies of the lumbosacral nerve roots].
abstract: Three cases of lumbosacral nerve root anomalies at their emergence are presented. They have been diagnosed by using water soluble non ionic contrast medium myelography. They all belonged to Cannon's type I classification (conjoined roots) and they were all localized at L5-S1 level. The authors emphasize that such anomalies give no symptoms and they underline the importance of their recognition in view of a correct surgical treatment.
