Lateral sacral meningomyelocele as a gluteal swelling--an unusual presentation.

Paravertebral meningoceles are rare examples of craniospinal dysraphism. A young boy presented with a cystic swelling over left gluteal region with lumbosacral scoliosis. On exploration, he was found to have a laterally placed sacral meningomyelocele. The presence of an unusually located meningocele should be suspected when a paravertebral mass is associated with neurological deficit or deformity of the spine.
