[Extracranial metastasis of meningeal tumors. Malignant meningioma with regional lymph node metastasis].
Metastases of a meningioma occurred in a 45-year-old man 4 years after removal of a falx meningioma and 1 year after removal of a malignant relapse. They were situated in the cervical, nuchal, and supra-clavicular lymph nodes. The review of 63 cases of metastasising meningial tumours from the literature, shows that lymph nodes are the most frequent site of metastases after lung and liver. The spreading of the tumour into the regional lymph nodes requires a penetration of the primary tumour into the galea, where the tumour cells may reach the lymphatic system. According to the literature, lymph node metastases are caused by benign as often as by malignant meningiomas, the majority being cases who underwent operation. Discussed, are the different theories as to why intracranial tumours only rarely show extracranial metastases.
