颅内生殖细胞瘤CT与临床表现的关系及其CT检查

Correlating CT scan to Clinical Findings in the intracranial Germinoma

目的：本文报道了16例颅内生殖细胞瘤，着重探讨其CT表现与临床表现的关系，合理使用CT检查。资料与方法：16例颅内生殖细胞瘤，分别行脑CT平扫和增强扫描，还采用冠状位及轴位扫描，轴位扫描层厚为10mm，冠状位扫描层厚3mm。结果：8例肿瘤位于松果体区，4例肿瘤同时位于鞍区和松果体区，1例位于松果体区和胼胝体膝部，2例位于鞍区，1例位于基底节区。16例有强化，其中12例为均匀强化；14例有阻塞性脑积水，2例有室管膜转移。结论：在疑有颅内高压以及鞍区肿瘤时，除常规按鞍区肿瘤行冠状位CT直接增强扫描外，还要常规行轴位CT扫描，这样可同时发现鞍区与松果体区或基底节区并存的肿瘤，此不仅可防漏诊，而且对生殖细胞瘤的定性诊断也极有帮助。

16 cases of intracranial Germinoma are reported in this paper,it's important to correlatingCT scan to clinical manifestations. Materials and Methods: Preenhancent CT scan and echancement CTscan were performed in both axial and coronary in this series.Results:The lesions were located at pinealregion in 8 cases,sella Turcica and pineal region in 4,pineal and corprs callosum in 1,sella Turcica in 2,basal ganglia and pineal region in 1.Conclusion:It's routine to scan in both coronary and axial sections forbeing suspected of mass in sella Turcica region or hydrocephalus. It can be founded coexiting lesions in sel-la and pineal regions or in basal ganglia region in this Way,so that it can be avoid mixdiagnosing.
