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.
横纹肌样脑膜瘤是脑膜瘤中一种罕见的变异类型,于2000年首次被引入世界卫生组织的神经系统肿瘤分类中。由于其侵袭性的临床病程和高增殖指数,它被归类为III级肿瘤。我们描述了一名50岁男性,有头痛、肢体无力和意识改变。CT显示双侧顶叶区域有不均匀强化的肿块病变,怀疑为高级别胶质瘤。组织病理学和免疫组化检查显示肿瘤具有横纹肌样脑膜瘤的特征。文献回顾未发现该肿瘤有双侧发生的情况。
