Anterior Sacral Meningocele is a unilocular or multilocular extension or herniation of the dura mater and arachnoid out of the sacral spinal canal through a defect in the sacrum into the retroperitoneum and infraperitoneal space, either anteriorly through the body of the sacrum or anterolaterally through an enlarged intervertebral foramen or coalesced foramina.
These findings are in agreement with the data found in the current literature (1,2,3,4,5) as it is very well known that EDH in elderly patients is less frequent because of the strong adhesion of dura mater to the bone, preventing the spread of bleeding.
