Bilateral rhabdoid meningioma mimicking glioma: an unusual occurrence.

Rhabdoid meningioma is an infrequent variant of meningioma, introduced for the first time in the 2000 World Health Organization's classification of tumors of the nervous system. Owing to its aggressive clinical course and high proliferative index, it has been classified as a grade III neoplasm. We describe a fifty-year-old male with headache, weakness of limbs, and altered sensorium. CT showed hetero-dense enhancing mass lesions in both right and left parietal areas raising suspicion of high grade glioma. Histopathologic and immunohistochemical examination revealed a tumor with features of rhabdoid meningioma. A review of literature did not reveal any bilateral occurrence of this tumor.
