Abstract:
Objective To study the imaging features of the ventricular meningioma, in order to improve the understanding knowledge. Methods Compared with operative and pathological findings,the CT and MRI features of ventricular meningioma were analyzed in 22 patients (8 males and 14 females,range from 17~72 years old with average age 45 years).21 cases were examined by MRI(17 with enhanced scan),11 cases by CT(4 with enhanced scan).Results The ventricular meningioma were mostly fibrous type. Mostly, the locations were in the trigone of the lateral ventricle with regular shape. On imaging, the most were parenchymatous with markedly enhancement. Calcification may be found, but cystic changes and hemorrhage were very rare.Conclusion The ventricular meningiomas have characteristic imaging features. CT and MRI are valuable in diagnosis, especially MRI.
