| 摘 要： | 目的探讨骶椎神经鞘瘤的侵犯特点与MRI表现特征。材料与方法观察26例骶椎神经鞘瘤的MRI表现,根据生长部位、侵犯范围及有无囊变、"足突边缘"征,进行分型、分组测量瘤体最大径。比较型间及组间瘤体最大径的差异。对照分析瘤实质T2WI信号、强化效应及HE染色组织学表现。结果 1型4例,2型5例,3型10例,4型7例。骶前软组织肿块出现率高于骶板后(χ2=13.066,P=0.011)。骶椎中线与中线旁骨质破坏各5例、14例。第3型瘤体最大径大于其他型(t=2.655,P=0.014)。8例巨大侵袭性骶椎神经鞘瘤(giant invasive sacral Schwannoma,GTSS)瘤体最大径超过18例非GISS(t=3.027,P=0.006)。"足突边缘"征阳性12例与阴性14例间瘤体最大径差异无显著性(t=1.896,P=0.07)。囊变组12例的瘤体最大径、病程均长于非囊变组14例(t=2.928,P=0.007;t=-2.187,P=0.039)。Ⅰ区呈T2WI稍高信号、明显强化,对应Atoni A区;Ⅱ区呈T2WI高信号、无强化或轻微强化,对应Atoni B区。结论骶椎神经鞘瘤具有偏心性破坏和骶前侵犯特性。T2WI上稍高信号与高信号及其差异性强化是该瘤的MRI表现特征。
