Occult anterior sacral meningocele

Anterior sacral meningocele is a rare congenital malformation consisting of
a spinal fluid-filled sac in the pelvis communicating by a small neck with
the spinal subarachnoid space through a sacral defect. This entity should
be considered if the characteristic scimitar sacrum is observed on a pelvic
roentgenogram. If signs and symptoms also suggest a meningocele, special
studies such as ultrasonography and myelography are indicated to establish
the diagnosis of an anterior sacral meningocele. Computerized tomography
provides additional evidence of spinal-abdominal extension of this lesion.
