Intracranial meningioma with metastasis to the third lumbar vertebra: A case report

Meningiomas are typically benign. Although the local recurrence rate is significant, distant metastasis is rare. We present a 60 year-old woman who had a primary benign intracranial meningioma located at the parasagittal area. Two craniotomies were performed, one for removal of the primary lesion and another, 5 years later, for a focal benign recurrence. Metastasis to the third lumbar vertebra with malignant change was detected eleven years after the first operation. It is possible that seeding from the superior sagittal sinus to the vertebra occurred by way of the vertebral venous system. Complete resection of the vertebral lesion was performed. The post-operative course was smooth, and the patient is currently being followed up regularly in the outpatient department.
