| Objective To analyse the CT appearance of ependymomas and to improve the accuracy of diagnosis. Methods To review the CT appearance of 15 cases of ependymoma that confirmed by surgery and pathology. Results 12 cases were superior, 8 cases were brain parenchyma among of them; 3 cases were subtentorial, among them the fourth ventricle 2 cases. The age of 6 cases vary from 20 to 35 years. Ependymomas superior to the tentorium in the brain parenchyma were the most common, and in malignant parts there were cystoid changes and edema around the tumor. In the other parts were largely solid neoplasm. On unenhanced CT, the solid parts were indense and caicificable and were easy to dicern on enhanced CT . Conclusion The CT appearances of ependymoma were specific, we can dram an accurate conclusion according where the tumor taking place, the age etc. |
