“…27 Russell & Rubinstein 5 and Sheithauer & Rubinstein, 33 favour an origin from pluripotential mesenchymal cells or from their more differentiated descendants abnormally present in meningeal tissue. Nevertheless, the recent observation by Katayama et al 34 5 observations of transitional aspects between meningioma and haemangiopericytoma. By analogy, such a metaplastic phenomenon can explain the occurrence of cartilaginous differentiation in glial tumors.…”

Introduction: Chondromas are rare intracranial tumors. The authors present two cases of intracranial intradural chondroma, one originating from the falx cerebri and the other from the dura mater of the convexity. Method and Results: Diagnostic procedures, including magnetic resonance imaging, and surgical findings are described. In both cases, pre-operative diagnosis could have been at least suspected, and the tumor was completely removed, without recurrence after a follow-up of many years. The pathogenesis and pathological findings are discussed, and cases from the literature are reviewed. Conclusion: Benign intradural chondroma has a good prognosis, with no recurrence after surgical excision in most cases. RESUME: Presentation de deux cas de chondrome intracranien et revue de la litterature. Introduction: Les auteurs pr6sentent 2 cas exceptionnels de chondrome intracranien intradural, une tumeur intracranienne particulierement rare. Un cas originait de la faux du cerveau et l'autre de la dure-mere de la convexity. Methode et Resultats: Les donndes d'imagerie, incluant la resonance magn&ique nucl6aire, de raeme que les donnees chirurgicales sont presentees. Dans les deux cas, le diagnositc pre-operatoire pouvait etre fortement suspecte\ et une excision complete de la 16sion a ete pratiqufie, sans signe de r^cidive apres une periode de suivi de nombreuses annfies. La pathog6nese et la pathologie sont discuses, et les auteurs font une revue breve des cas de la literature. Conclusion: Le chondrome intradural b6nin est une tumeur a bon pronostic avec un risque tres faible de recurrence apres excision chirurgicale complete.
