[Meningioma with extracranial multiple metastases--a case report]

Area of Science:

• Neurology
• Oncology
• Pathology

Background:

• Meningiomas are typically benign tumors arising from the meninges.
• Malignant meningiomas are rare, and extracranial metastasis is exceptionally uncommon.

Observation:

• A 21-year-old female presented with a convexity meningioma and intracerebral hematoma.
• Histological diagnosis revealed a malignant fibroblastic meningioma.
• The patient underwent surgical resection and whole-brain radiotherapy.

Findings:

• Recurrence was noted two years post-treatment.
• Extracranial metastases subsequently appeared in the lung and liver.
• The patient succumbed to intraperitoneal bleeding from liver metastases.

Implications:

• This case highlights the aggressive potential of malignant fibroblastic meningiomas.
• It underscores the importance of considering metastatic disease in rare meningioma subtypes.
• Further research into the behavior and treatment of aggressive meningiomas is warranted.
