[Anterior sacral meningocele in pregnancy].

Anterior sacral meningocele is a rare condition characterized by the herniation of meningeal membranes and cerebrospinal fluid through a defect in the anterior aspect of the sacrum. We present the case of a 26-year-old patient with an anterior sacral meningocele which had been discovered during gynaecologic surgery because of a cystic pelvic mass. Subsequently, the patient underwent two pregnancies. The management of a pregnancy complicated by a coexisting anterior sacral meningocele presents a challenging problem for the obstetrician. Because of the high maternal mortality due to rupture of the meningocele under labor, primary cesarean delivery is indicated as soon as fetal lung maturity is established and was performed in our patient in both pregnancies in the 35 week, without complications for mother and children.
