目的 探讨脑室脑膜瘤的影像学表现,以提高对脑室脑膜瘤的认识和诊断正确率。方法 经手术病理证实的脑室脑膜瘤 22例,其中男 8例,女 14例,年龄 17~72岁(平均 45岁 )。行MRI检查 21例,其中增强 17例;行CT检查 11例,其中增强 4例;同时行CT和MRI检查 10例,结合手术和病理结果进行分析。结果 脑室脑膜瘤以纤维型多见,主要位于侧脑室三角区,多数表现为实质性肿块,边界清晰,明显强化。可见钙化,出血及囊变少见。结论 脑室脑膜瘤有特殊的影像学表现,CT和MRI在诊断中具有一定的价值,尤其是MRI。
Objective To investigate the imaging findings of ventricular meningioma in order to improve the recognition and diagnosis of ventricular meningioma. Methods Twenty-two cases of ventricular meningioma proved by surgery and pathology, including 8 males and 14 females, aged from 17 to 72 years (average 45 years). 21 cases were examined by MRI, among which 17 cases were enhanced; 11 cases were examined by CT, of which 4 cases were enhanced; 10 cases were examined by CT and MRI at the same time, combined with the operation and pathological results. The results of ventricular meningioma to see more fibrous type, mainly located in the lateral ventricle triangle area, the majority of the performance of a substantial mass, clear boundary, significantly enhanced. Visible calcification, bleeding and cystic changes rare. Conclusion Ventricular meningiomas have special imaging findings. CT and MRI have certain value in the diagnosis, especially MRI.
