title: Chordoid meningioma: A diagnostic dilemma.
abstract: Chordoid meningioma (CM), classified as Grade II/atypical meningioma according to the World Health Organization classification, is a rare subtype, which represents only 0.5% of all meningiomas. Morphologically, it can mimic other chondroid and myxoid tumors within the brain and its vicinity thus posing a diagnostic challenge. Accurate diagnosis, therefore, assumes importance as these tumors have an aggressive clinical course and propensity to recur compared to classical meningiomas. Furthermore, the prognosis and treatment strategies vary when compared to tumors with morphological overlap. We present a case of CM in a 14-year-old girl and discuss its clinicopathological and immunohistochemical features.
