Synopsis

A neural tube defect where there is herniation of the meninges and spinal cord through a spinal defect due to failed closure of the caudal neural tube. The etiology is multifactorial, and reduced folic acid is associated with the condition. Diagnosis is often made in utero. The defect is visible on examination. Associated symptoms may include irritability, stridor, lower extremity weakness or numbness, urinary or bowel incontinence, back pain, spasticity, and/or cognitive or behavioral changes. It is often associated with Chiari II malformations. Hydrocephalus can be a complication, and neurologic decline warrants evaluation for this problem.

Without aggressive treatment including surgical closure of the defect, most die within 1 year. Survival is likely in those with early surgical repair, though many are still wheelchair-bound.
