Magnetic resonance imaging (MRI) is the primary diagnostic tool for occult spinal dysraphism in children. Computed tomography (CT) and myelography are reserved for complex cases where MRI is insufficient.

Area of Science:

  • Pediatric Radiology
  • Neurosurgery
  • Developmental Biology

Background:

  • Occult spinal dysraphism comprises a spectrum of congenital vertebral anomalies.
  • Accurate diagnosis is crucial for timely surgical intervention and improved outcomes.
  • Traditional imaging modalities have limitations in fully characterizing these complex malformations.

Purpose of the Study:

  • To evaluate the diagnostic utility of various imaging techniques for occult spinal dysraphism.
  • To refine classification and surgical indications based on neuroradiological findings.
  • To introduce a new term for complex conus medullaris and filum terminale abnormalities.

Main Methods:

  • Retrospective analysis of 47 pediatric patients (0-14 years) with occult spinal dysraphism.

  • Utilized plain X-rays, computed tomography (CT), CT myelography, and magnetic resonance (MR) imaging.
  • Correlated imaging findings with clinical presentation and surgical outcomes.

    • Main Results:

    • Magnetic resonance (MR) imaging proved to be the most effective modality for diagnosis.
    • CT and CT myelography were necessary only in select cases of significant anatomical complexity.
    • A novel term, "neurofibrous structure," is proposed for the indistinguishable conus-filum terminale unit.

    Conclusions:

    • MR imaging is the gold standard for evaluating occult spinal dysraphism in children.
    • CT and CT myelography play a supplementary role in complex anatomical scenarios.
    • The proposed "neurofibrous structure" term aids in describing complex conus-filum terminale malformations.
