Abstract:
Rhabdoid meningioma is an uncommon meningioma variant, which was initially described in 1998 by Perry et al.. It is classified as a variant corresponding to grade III in the recent World Health Organization(WHO) classification of tumors of the nervous system, because of its unique histopathological features and its highly aggressive clinical course. To date there were still a lot of arguments about their developmental patterns and the treatment strategy especially for rhabdoid meningiomas lacking other histological features of malignancy. Although the exact causes of rhabdoid transformation of a benign meningioma are unknown, malignant transformation long duration after surgical resection under an underlying predilection for malignancy is suggested in our case. And we suggest that any histological rhabdoid features in recurrent meningiomas or even in primary cases seem to indicate the malignant clinical course and the need for aggressive treatments, because transformation from a benign or atypical one to a malignant one seems to occur at last.
