Anterior sacral meningoceles are congenital lesions that consist of a spinal fluid-filled sac in the pelvis communicating by a small neck with the spinal subarachnoid space through a defect in the sacrum. They protrude into retroperitoneal and presacral space. ^1) 2).

The wall of the sac consists of two layers, an inner arachnoid membrane and outer dura mater, which extends into the retroperitoneal presacral space from the sacral spinal canal ³⁾.

Anterior sacral meningocele was first described in 1837 as a part of neural tube defect (NTD) spectrum.

It may be associated with a syndrome like Currarino syndrome ⁴⁾ which includes anorectal malformations, sacral bony defect and presacral mass; and Marfan syndrome wherein the etiology may be disorder of collagen biosynthesis and structure at the dural level ⁵⁾.
