Definition

Open spinal dysraphism (Aka formerly spina bifida aperta or cystica):

• Definition:
• occurs when the cord and its covering communicate with the outside;
• no skin or tissues cover the sac

• Myelocele

• Myelomeningiocele

• Hemimyelomeningocele

• hemimyelocele

Closed spinal dysraphism (formerly spina bifida occulta): occurs when the cord is covered by other normal mesenchymal elements

with subcutaneous mass

• lipoma with dural defect

• lipomyelomeningocele

• lipomyelocele/lipomyeloschisis

• terminal myelocystocele
• Are rare
• Characterised by syringocele (expansion of terminal central canal) herniating through a wide spina bifida and surrounded by a rostral meningocele.

• Meningocele
• Posterior meningocele
• comprises 2.5% of CSD
• consists of herniation of CSF-filled meningeal sac (may also contain nerve roots/filum but not spinal cord) through posterior spina bifida.

• Limited dorsal myeloschisis

without subcutaneous mass

• posterior spina bifida (isolated defect of the posterior neural arch of vertebra)

• intradural lipoma

• filar lipoma

• tight filum terminale

• persistent terminal ventricle

• disorders of midline notochordal integration
• dorsal dermal sinus
• dorsal enteric fistula
• neurenteric cyst
• Split cord malformations
• diastematomyelia
• diplomyelia

• disorders of notochordal formation
• Caudal regression syndrome
• type 1
• type 2
• Segmental spinal dysgenesis
