| A rare closed neural tube defect characterized by cystic dilatation of the central canal of the spinal cord, herniating through a posterior vertebral arch defect (spina bifida) into an expanded cerebrospinal fluid (CSF) filled dural sac (meningocele). It can be located at the caudal part of the spinal cord (terminal myelocystocele) or above conus (non-terminal myelocystocele). |
