目的分析总结颅内生殖细胞肿瘤的MRI特征,提高其诊断准确性。方法回顾性分析经手术病理证实的颅内生殖细胞肿瘤15例,所有病例均行常规SE序列平扫及增强扫描,必要时加扫脂肪抑制序列。结果6例位于松果体区,6例位于鞍区(松果体区及鞍区生殖细胞瘤、畸胎瘤及绒毛癌均分别为3例、2例及1例),2例位于基底节区(均为生殖细胞瘤),1例位于右侧脑室(畸胎瘤)。结论MRI对颅内生殖细胞肿瘤的诊断与鉴别诊断具有重要价值。
Objective To analyze and summarize the MRI features of intracranial germ cell tumors and improve their diagnostic accuracy. Methods Retrospective analysis of 15 cases of intracranial germ cell tumors confirmed by surgery and pathology, all cases underwent conventional SE sequence scan and enhanced scan, if necessary, plus fat suppression sequence. Results Six patients were located in the pineal region, six in the saddle region (3 in the pineal region and the saddlery germ cell tumor, 3 in the teratoma and the choriocarcinoma, 2 and 1, respectively) and 2 in the basal ganglia District (all germ cell tumors), and 1 in the right ventricle (teratoma). Conclusion MRI is of great value in the diagnosis and differential diagnosis of intracranial germ cell tumors.
