This study details the first pediatric case of a plexiform neurofibroma of the cauda equina, a rare spinal tumor. The 4-year-old patient experienced pain and underwent radiotherapy for the tumor.
Area of Science:
- Pediatric Neurosurgery
- Oncology
- Spinal Cord Tumors
Background:
- Plexiform neurofibromas are rare tumors.
- Cauda equina involvement is exceptionally uncommon, with only two prior reports.
- This case represents the first pediatric instance of this condition.
Observation:
- A 4-year-old boy presented with low-back pain radiating to L-4 and L-5 dermatomes.
- A concurrent midthoracic dermal sinus with a hemangiomatous lesion was noted.
- MRI revealed a lumbosacral mass engulfing the cauda equina roots.
Findings:
- The plexiform neurofibroma of the cauda equina was surgically inseparable from nerve roots.
- Radiotherapy was administered to manage tumor progression and pain.
- No association with neurofibromatosis Type 1 was observed.
Implications:
- Highlights the rarity and potential severity of pediatric cauda equina plexiform neurofibromas.
- Emphasizes the importance of comprehensive imaging in pediatric spinal conditions.
- Suggests radiotherapy as a palliative and control measure for unresectable tumors.
