From Wikipedia, the free encyclopedia
In human anatomy, the presacral space is inside the pelvis, behind the rectum and in front of the coccyx and sacrum. Normally it is empty, or it contains a pocket of fat.
[edit] Clinical significance
The presacral space may contain one of several kinds of tumor. The most common tumor here is sacrococcygeal teratoma. Others are retrorectal hamartoma (tailgut cyst), schwannoma, ganglioneuroma, and ependymoma. Also sometimes found here is an anterior meningocele, a relatively mild form of neural tube defect.
