Intracranial meningeal chondrosarcoma--probable mesenchymal type.
A 12 year old girl with episodes of left hemiparesis for 9 months was found to have a large, partly calcified brain tumour which at craniotomy presented on the parasagittal and medial surfaces of the right frontal lobe. No dural or falx attachment could be found and naked eye removal of the tumour was achieved. At a second craniotomy 10 weeks later there was recurrent tumour attached to the falx and involving the sagittal sinus. She died 5 months later. Pathologically, almost all this malignant intracranial neoplasm comprised differentiated cartilaginous tumour. Although only a very small amount of undifferentiated mesenchymal tissue was found in the surgical material available for histological study, it is suggested the tumour can be regarded as a predominantly mature mesenchymal chondrosarcoma of the meninges.
