Abstract

Although malignant transformation of meningiomas has been reported, it is extremely rare in meningiomas of ventricular system. Less than 2% of all meningiomas show malignant transformation from benign meningioma. We report a case of meningioma with early recurrence and malignant transformation and investigated possible underlying factors using immunohistochemistry for PCNA and p53 protein expression.
