Summary
Wilms tumor metastasis to the spine is rare. This case highlights a lumbosacral intradural metastasis from an intracerebral source, with limited improvement after radiation therapy.
Area of Science:
- Pediatric Oncology
- Neuro-oncology
- Spinal Metastasis
Background:
- Wilms tumor, a common pediatric kidney cancer, rarely metastasizes to the central nervous system.
- Intracranial metastases are more common than spinal metastases in pediatric oncology.
Observation:
- A 7-year-old boy with a history of intracerebral Wilms tumor metastases developed new symptoms of low back pain and lower extremity weakness.
- Imaging revealed an intradural lumbosacral lesion, distinct from any intracranial recurrence.
- Surgical biopsy of the intradural lesion was performed due to extensive nerve root involvement.
Findings:
- The intradural lumbosacral lesion represented a probable "drop metastasis" from the prior intracerebral Wilms tumor.
- Postoperative radiation therapy showed minimal tumor regression and no significant neurological improvement.
Implications:
- This case represents a rare instance of intradural spinal metastasis from an intracerebral Wilms tumor.
- The optimal treatment strategy for spinal Wilms tumor metastases remains uncertain.
- Radiation therapy may have limited efficacy in treating such rare metastatic presentations.
