目的：探讨MRI对颅内生殖细胞瘤的诊断价值。方法经病理或临床证实的颅内生殖细胞瘤21例，回顾性分析其治疗前MRI表现。结果21例中，8例位于松果体区，6例位于下丘脑区，5例同时累及松果体及下丘脑区，2例发生于基底核区。3例生殖细胞瘤合并脑膜转移。发生在松果体区或（和）下丘脑区的生殖细胞瘤典型的MRI表现为肿瘤信号均匀，边界清楚，增强后明显强化，本组共14例表现较为典型，另5例及基底核区2例生殖细胞瘤发生囊变。结论 MRI对颅内生殖细胞瘤的诊断与鉴别诊断具有重要的价值。尤其是当松果体及下丘脑区同时出现肿块时，应高度怀疑生殖细胞瘤。

Objective To explore the diagnostic value of MR imaging (MRI)in confirming the patients with intracranial germi-noma.Methods Twenty-one patients with intracranial germinoma confirmed histologically or clinically were selected as the object of this study.MRI findings of germinoma were analysed retrospectively.Results Of 21 cases,the tumors were located at pineal region in 8,hypo-thalamus in 6,pineal region as well as hypothalamus in 5,and basal ganglion region in 2 cases.Germinoma with intracranial metastases were proved in 3 cases.Typical findings of germinoma located at pineal region or (and)hypothalamus on MR imaging were uniformity signal intensi-ty,and definite margin,and marked enhancement in 14 cases.Cystic parts were found on another germinoma located at pineal region or (and) hypothalamus in 5 and basal ganglion region in 2 cases.Conclusion MRI has significant clinical value in the diagnosis and differential diagno-sis of intracranial germinoma.It is probably the intracranial germinoma when masses are found at pineal region as well as hypothalamus.
