摘要 目的:总结颅内生殖细胞瘤的临床表现及影像学特点。方法:对38例颅内生殖细胞瘤患者的临床资料和影像学改变进行分析。结果:38例中年龄小于18岁32例(84%),偏瘫14例,尿崩症11例,头痛、呕吐8例,视力减退8例,视乳头水肿8例,丘脑底部综合征7例,复视4例,性早熟3例。肿瘤位于松果体区13例,鞍区11例,基底节区14例。位于松果体区或鞍区的生殖细胞瘤,CT表现为圆形或类圆形病灶,增强扫描后呈均匀或不均匀强化,钙化不多见;磁共振表现为不规则形病灶,T1、T2加权像呈均匀等信号,增强扫描后病灶明显强化。基底节区生殖细胞瘤在CT上表现为形态不规则病灶;磁共振上表现为T1加权像混杂低信号,T2加权像呈混杂高信号。结论:颅内生殖细胞瘤患者以儿童、青少年多见,病变多位于松果体区、鞍区或基底节区。临床主要表现为颅内压升高、尿崩症、视功能障碍或偏瘫,结合影像学检查有助于其诊断。
