Liver Metastasis from Typical Meningioma.

Abstract

Extracranial metastases from atypical meningioma are not usually found; they are sometimes found in lung, bone or scalp, but atypical meningioma in the liver is extremely rare. We report a case of a 55-year-old patient with atypical meningioma, treated with surgical resection in 2005, who accepted a second surgical resection in 2015 by the same surgeon, caused by a liver metastasis 4 years after the second surgical resection. We have analyzed the cytological findings of a metastastic meningioma with particular focus on pathological and immunohistochemical assessment. These results could improve the knowledge of surgeons about meningioma types and guide them to solve clinical incidents.
