Malignant Meningioma with Lumbar Spinal Metastasis (a case report)

Meningioma is considered as a benign central nervous system tumor that accounts for approximately ۱۸% of all brain tumors. About ۵% of meningioma tumors are malignant and have more aggressive clinical signs and worse prognosis compared to benign tumors. Extracranial metastasis of meningioma is rare but in the case of occurrence, it is more prevalent in lung, liver and lymph nodes. Osseous metastasis including vertebra has been reported very rarely. Here we report a young male patient with intracranial malignant meningioma who developed signs of lumbar spinal involvement of metastatic malignant meningioma after one year.
