| 目的 本文通过15例神经节细胞胶质瘤的分析,对其影像表现做一总结。方法 13例术前经MR平扫及增强检查。4例经CT检查。结果 实性与囊实性肿瘤12例,实性部分呈长或等T1长T2信号,信号不均匀,边缘欠清或清。注药后肿瘤可有不规则增强或均匀增强。实性部分内可有囊腔,钙化或伴有出血。囊性肿瘤3例,囊性部分呈等脑脊液信号。结论 神经节细胞胶质瘤常见于颞叶、小脑、额叶、鞍上池等区。颞叶的肿瘤伴有钙化及脑内囊性肿瘤应与神经节细胞胶质瘤相鉴别。 |
| 英文摘要: |
| Objective Fifteen cases intracranial ganglioglioma were reviewed to determine their MR, CT characteristics. Methods Thirteen cases were evaluated with contrast enhancement and 4 cases were studied by CT. Results Twelve cases were solid tumors. Solid portion had heterogeneous hyperintensity or isointensity in T1 and hyperintensity in T2 and had homogeneous and inhomogeneous enhancement after contrast injection.Solid portion might have cyst,calcification, haemorrhage. Three cases were cystic tumors. Cystic portion had the isointensity as cerebral-spinal fluid or hyperintesity. Conclusion Ganglioglioma could be found frequently in temporal lobe, cerebellum, frontal lobe, supersellar cistern etc. Tumors in the temporal lobe with calcification and large cystic tumor should be differentiated from ganglioglioma. |
