Objective To discuss the MRI features of solid intarmedullary intracranial hemangioblastoma,so as to provide reference for clinical diagnosis.Methods Clinical data were collected from 15 solid intarmedullary intracranial hemangioblastoma patients in our hospital.Their MRI features were analyzed.Results Their MRI images showed oval,round,striped,patchy and long tubular solid mass with clear edges.Lesion signals were various,including normal,long T1 signals,long T2 signals,and slightly short T1 signal and slightly long T2 signal.The lesion had obvious mass effects.Uneven signals were detected within 12 tumors.Multiple flow void sections in 5 lesions were round-like without signals.Obviously enhanced paravertebral mass shadow was presented in 2 cases.Remarkably enhanced solid components were detected by most tumor enhance scanning,except one case where diffused,striped,long T1 signals were found in the thoracic vertebrae,which was not enhanced after enhanced scanning.Conclusions Intramedullary solid vascular tumor has characteristic MRI findings,and MRI can provide evidence for preoperative localization and diagnosis.%目的 探讨髓内实性血管母细胞瘤的MRI的特征,为临床疾病诊断提供参考.方法 选取我院收治的15例髓内实性血管母细胞瘤为研究对象,分析其MRI特征.结果 肿瘤的MRI表现为类椭圆形、圆形、条状、斑片状以及长管状,边界清晰的实性软组织肿块;病变信号混杂,呈现等、长T1信号及长T2信号以及稍短T1信号、稍长T2信号;病灶占位效应明显,周围水肿较轻;12例肿瘤内部信号不均匀;5例病灶周围多个流空血管断面,呈类圆形无信号表现;2例椎旁可见明显强化团块影;大部分肿瘤增强扫描实性成分均显著强化,仅1例胸椎弥漫条状长T1信号影,增强后未明显强化.结论 髓内实性血管母细胞瘤MRI具有特征性表现,临床上行MRI检查能为患者的术前定位及诊断提供依据.
