[Anterior sacral meningocele. Apropos of 11 cases].

The authors report 11 cases of anterior sacral meningocele, cystic mass connected with lumbar sac through a sacral bony defect: 2 children and 9 adults. Clinic presentations are analysed. Examination including, X ray, ultrasonography, scanner is discussed. The authors believe that these lesions must be treated surgically because a risk of rupture in the rectum with important meningitis exists. There is also a septic risk if an error of diagnosis ends at a puncture. The transacral approach is easy and it gives the best results.
