Summary
Radiation therapy for port-wine stains may increase the risk of developing intracranial meningiomas years later. This case highlights a potential long-term complication of radiotherapy in pediatric patients.
Area of Science:
- Neurology
- Oncology
- Dermatology
Background:
- Cerebral radiation is a known risk factor for secondary brain tumors.
- Meningiomas are the most common primary intracranial tumors, typically benign.
- Port-wine stains are congenital vascular malformations often treated with radiotherapy.
Observation:
- A young woman presented with symptoms of an intracranial mass lesion.
- The patient had a history of radiotherapy for a right fronto-temporal and periorbital port-wine stain 17 years prior.
- A right sphenoid wing meningioma was diagnosed and surgically removed.
Findings:
- The temporal relationship between radiotherapy and meningioma development suggests a possible causal link.
- The latency period of 17 years is consistent with radiation-induced tumorigenesis.
- Histopathological analysis confirmed the diagnosis of meningioma.
Implications:
- Radiotherapy for benign conditions like port-wine stains may carry a risk of secondary intracranial tumors.
- Long-term surveillance may be warranted for patients treated with cranial irradiation.
- Further research is needed to elucidate the precise mechanisms and risk factors for radiation-induced meningiomas.
