Primary cutaneous extravertebral meningioma. Case report.
Journal of Neurosurgery
|May 1, 1984
Summary
A rare case of cutaneous meningioma, initially diagnosed as a lumbar meningocele in infancy, is presented. A fibrous stalk connected the tumor to the dura mater, suggesting a potential pathogenetic link.
Area of Science:
- Neurosurgery
- Dermatology
- Pediatric Surgery
Background:
- Cutaneous extravertebral meningiomas are rare tumors.
- This case involved a diagnosis in infancy initially presenting as a lumbar meningocele.
Observation:
- The patient presented with a lumbar meningocele diagnosed in infancy.
- Surgical intervention was initially refused but later pursued for cosmetic reasons.
- Examination revealed significantly thickened, corrugated skin and a cutaneous meningioma.
Findings:
- A cutaneous meningioma was identified.
- The tumor was connected to the dura mater via a fibrous tract.
- This fibrous stalk is hypothesized as the pathogenetic link between the meningocele and the meningioma.
Implications:
- This case highlights a potential developmental pathway for cutaneous meningiomas.
- Understanding such connections is crucial for accurate diagnosis and surgical planning.
- Further research into the embryogenesis of spinal and cutaneous anomalies is warranted.
