| 摘 要： | 目的：探讨儿童脑肿瘤的MRI特点，以期提高其诊断水平。方法：回顾分析经手术病理证实的60例儿童脑肿瘤MRI表现，并与病理结果进行对照。结果：60例中，发生于脑干17例(28．3％)，鞍内及鞍上区15例(25％)，小脑13例(21．6％)，幕上半球8例(13．3％)，间脑侧脑室、四脑室各2例，枕骨1例。大多数肿瘤在T1WI上表现为低信号、等信号或／和低信号，在T2WI上为不均匀高信号，增强扫描表现为均匀或不均匀强化。结论：胶质瘤是儿童期脑肿瘤最常见的肿瘤，脑干是其最常发生的部位，其次是颅咽管瘤，常发生于鞍内及鞍上区，小脑是儿童髓母细胞瘤常发生的部位。

| Abstract: | Objective:To explore MRI characteristics of brain tumors in children.They were compared with pathologic tissues.Methods:60 cases with brain tumors proved by pathology were analyzed retrospectively.Results:Most tumors demonstrated low signal intensity or isointensity signal or hypo-and isointense on T_1-weighted images,heterogeneously high signal intensity on T_2-weighted images.They may display homogeneous or heterogeneously enhancement at magnetic resonance images.Conclusion:Glioma is the most common nerve system tumors in children and brain stem is the most common place.Craniopharyngioma is secondly common brain tumors in children and is most found in saddle or upper saddle;Medulloblastoma is most common cerebellar tumors. |
