| 目的分析脑室肿瘤的CT 和MRI 特征,提高对各种脑室肿瘤诊断的准确率。方法收集26 例经手术
与病理证实的脑室多种肿瘤:其中侧脑室15 例,三脑室3 例,四脑室8 例。单独作CT 检查5 例,同时作CT 和MRI
检查21 例。根据26 例多种脑室肿瘤的发生部位,进行脑室定位分类。结果5 例中央性神经细胞瘤和2 例胶样囊
肿发生于中线室间孔区;6 例髓母细胞瘤分别发生于小脑上蚓部和四脑室顶部近中线区;5 例室管膜瘤发生在单侧
脑室,年龄分别为28～36 岁;3 例室管膜瘤发生在四脑室,年龄分别为7～13 岁;2 例脉络丛乳头状瘤发生侧脑室三
角区,年龄13～15 岁;2 例脑膜瘤发生在侧脑室三角区,年龄为15～71 岁,1 例巨细胞型星形细胞瘤发生在右侧脑室
底部,年龄为30 岁。结论CT 与MRI 有助于对脑室肿瘤的鉴别诊断,结合临床资料进行综合分析,可提高诊断的
准确率。 |

| Objective To analyse imaging features of ventricle tumor and to improve accuracy of diagnosis in various ven-
tricle tumors. Methods We collected 26 cases ventricle tumors proved surgically and pathologically. Among of them ,later-
al ventricle tumors 15 cases ,the third ventricle tumors 3 cases ,the fourth ventricle tumors 8 cases. 5 cases were performed
with CT ,21 cases were performed with CT and MRI. We could categorise them according to their location. Results 5 cas-
es central gaugliocytoma and 2 cases colloid cyst were located at middle line of ventricle ,6 cases medulloblastoma were locat-
ed at the top of the fourth ventricle or super cerebellum vermis ,5 cases ependymoma were located at one lateral ventricle ,3
cases ependymoma were located at the fouth ventricle ,2 cases papilloma of choroid plexus werre located at triangle area of
lateral ventricle ,2 cases meningioma were located at triangle area of lateral ventricle ,1 cases astrocytoma were located at lat-
eral ventricle anterior horn. Conclusion CT and MRI was helpful in differential of ventricle tumor and could improve the
accuracy of diagnosis when combined with clinical data. |
