COSTA JR, Leodante Batista da  and  MORAIS, Josaphat Vilela de. Meningioma with rhabdoid transformation: case report. Arq. Neuro-Psiquiatr. [online]. 2003, vol.61, n.2A, pp.277-280. ISSN 0004-282X.

Meningiomas represent aproximatelly 30% of all intracranial tumors in autopsy studies. With an incidence of 2.3 per 100000, they are considered commom tumors in clinical practice. Twenty percent of the all intracranial tumors diagnosed in vivo are meningiomas. Most of these lesions are benign and the prognosis is intimatelly related to acessibility and ressectability of the lesion. Malignant meningiomas are rare lesions, representing between 1 to 11% of all meningiomas, varying with the definition of pathological criteria for malignancy used, and are categorized in atypical or malignant. Only recently rhabdoid transformation of meningiomas have been reported. We present a case of an extremelly aggressive rhabdoid meningioma in a 56 year-old woman. The tumor was surgically removed twice, with a lethal outcome due to local recurrence, despite maximum radiation and quimiotherapy, six months after the initial presentation.

Keywords : malignant meningioma; meningioma; rhabdoid tumor.
