| 摘 要： | 目的：分析总结颅内生殖细胞瘤的MRI表现特征,提高对其的认识。方法：分析了12例颅内生殖细胞瘤的MRI。结果：肿瘤12例中9例为类圆形;10例边界清楚,没有脂肪信号;9例有大小不等囊变,囊变散在分布;肿瘤实质部分T1WI以低信号为主,T2WI等信号或稍高信号,增强扫描肿瘤实质部分明显强化;大部分肿瘤周围脑组织轻中度水肿;肿瘤的占位效应较轻。结论：MRI对颅内生殖细胞瘤有一定诊断价值。

| Abstract: | Objective:To analyse the MRI features of intracranial germinoma so as to improve the diagnosis of this disease.Methods:12 cases of germinoma verified by operation and pathology were reviewed and analyzed.All cases underwent plain and contrast-enhanced MRI,the fat restrained sequence was performed if necessary.Results:On T2WI,the lesions were showed isointense singal or slightly hyperintense singal.On T1WI,the lesions were showed isointense singal or slightly hypointense singal.After Gd-DTPA administration,t... |
