1) Intracranial and calvarial chondromas are very rare tumors. 4 cases of chondromas among total 2900 cases of brain tumors in our clinic two cases in the parasellar region, one case arising from the occipital hone and one case adherent to the dura of parietal region) were described. Furthermore, total 96 cases of cranial caltilaginous tumors were collected from the world literatures. Based upon the statistical data of all these cases including our four cases, the clinical and pathological characteristics of these tumors were discussed.

2) The caltilaginous tumors arising from men-inges or choroid plexus were also classified as chon-dromas when they showed chondromatous appearan-ce by histological examinations.

3.) These tumors occur in the third through the fifth decade of life and show some predilection for females. The patients present clinical manifestations of slowly growing space-occupying lesion. Calcified shadow and destructions of bone are the roentogeno-graphic findings of these tumors. Surgical treat-ments, when they are removed as much as possible, are always of great benefit. However, chondrosar-comas, found in 20% cases of these caltilaginous tumors grow sometimes infiltratively into the brain tissue and show rapid recurrence when total removal is macrospically performed.
