Closed spinal dysraphisms such as diastomatomyelia, dermal sinus
, terminal myelocystocoele, lipomas, thickened filum terminale, tethered cord and sacral spina bifida have been described in the literature.
This is a diverse group including meningocoele, lipoma of the cauda equina, dermal sinus
and so on.
Of the full cohort, 18 infants were diagnosed with neural tube defects, including 12 with spina bifida cystica, 4 with tethered cord syndrome associated with sacral lipoma, and 2 with dermal sinus
This can be caused by a variety of etiologies: myelomeningocele, lipomyelomeningocele, diastematomyelia, tight filum terminale, dermal sinus
tract, tumor, and scar tissue.
Previous meningitis (especially recurrent) may suggest a dermal sinus

cysts, nasal encephaloceles, and nasal gliomas.
