title: Chondrosarcoma arising from the falx cerebri.
abstract: A chondrosarcoma arising from the falx cerebri in a 15-year-old boy is reported. The patient had been suffering from convulsive seizures and weakness of the limbs on the left side for about 7 months prior to admission. A high-density mass attached to the falx was demonstrated by computed tomographic scan. Clinically it was very similar to a falx meningioma, and the final diagnosis was obtained from histopathological examination. The tumor was completely excised at operation, which is extremely important to prevent both local recurrence and distant metastasis.
