According to the World Health Organization Classification of Tumors of the Nervous System （Lyon, 2000）,chordoid meningioma together with another rare variant, lymphoplasmacyterich meningioma, usually contain abundant lymphoplasmacytic infiltration, and are associated even with hematological abnormalities, especially in young adults. Few cases of chordoid meningioma have been reported in detail until Couce and his colleagues reported a sizable series of forty-two cases. Even then, the clinical and pathological features of these tumors were not well characterized, because of variations in different papers. In the present article, we report two adult patients with chordoid meningioma.展开更多
