摘要：

Most meningiomas are benign;however anaplastic meningiomas are usually highly invasive and grow rapidly. These tumors can metastases outside the blood-brain barrier occurring to the lungs. We present an unusual case of multiple pulmonary metastases from anaplastic and recurrent intracranial meningioma in a 59-year-old male patient. Multiple pulmonary metastases from meningioma are very rare, but we should be aware of this possibility in patients with intracranial malignant meningioma especially, with potential predictive factors include anaplastic meningioma, venous sinus invasion, recurrence or previous intracranial surgery, and loss of heterozygosity.
