Abstract
Chordoid meningioma is classified in the latest classification of brain tumours as a grade II meningioma, along with large cell meningiomas. It is a rare tumour often associated with systemic symptoms, as described by Castelman. He described a case of chordoid meningioma discovered incidentally in a 45-year-old female patient following road accident. Brain CT scan showed left isodense intradiploid pterional lesion with bone lysis, which was homogeneously enhanced after injection of contrast medium. Magnetic resonance imaging showed T1-hypointense and spontaneously T2 FLAIR hyperintense lesion, which was very strongly enhanced after injection of Gadolinium. Complete resection of the tumour was performed. Histological and immunohistochemical examination showed chordoid meningioma.
