Currarino triad

The Currarino syndrome is an inherited congenital disorder where either the sacrum (the fused vertebrae forming the back of the pelvis) is not formed properly, or there is a mass in the presacral space in front of the sacrum, and there are malformations of the anus or rectum. It occurs in approximately 1 in 100,000 people.Anterior sacral meningocele is the most common presacral mass in patients with Currarino syndrome occurring in 60% of cases. [Source: Wikipedia ]
