Anterior sacral meningocele is an anterior sacral defect with a herniation of the meningeal sac from the sacral foramen to the retroperitoneal or presacral space. Most cases present in adulthood.

Clinically they can present with constipation, urological symptoms, or rarely neurological symptoms. The anorectal anomaly, the ventral sacral defect, and the presacral mass are collectively known as the Currarino triad. The teratoma or enteric cyst could enter this triad.

The relationship between the meningocele and the sacral nerve roots helps to establish a safe and less complicated surgical treatment.
