| 目的分析鞍区生殖细胞瘤的MR 影像特点。方法经手术及病理证实的鞍区生殖细胞瘤38 例,男12
例,女26 例,年龄3～32 岁。结果根据位置不同将其分为三类: I 类:肿瘤位于第三脑室内,包括从第三脑室底向
上长入第三脑室,共20 例; II 类:仅位于第三脑室底,累及视交叉、漏斗、垂体柄、视神经和视束,共15 例; III 类:仅位于
鞍内,共3 例。结论MRI 对I 类和II 类生殖细胞瘤的诊断有重要价值,MRI 对III 类不易作出诊断,必须结合临床。 |

| Objective To study the MRI findings of germinomas in sellar region. Methods All cases were proved by
operation and pathology. There were 12 males and 26 females. The patient age ranges 3～32 years. The main symptoms of
all cases were diabetes insipidus , defective visiona and change of sexual charactor. Results Germinoma in sellar region were
classified into 3 types according to its site : Type I was inside the third ventricle including those stemming from the bottom
of the third ventricle , and 20 cases in all ; Type II was only at the bottom of the third ventricle , and 15 cases in all. Type
III was only in sella , and 3 cases in all. Conclusion MRI examination is of great value in diagnosis of type I and type II ,
bat MRI has difficulty in diagnosing type III. |
