目的:探讨小脑梗死核磁共振诊断的临床价值。方法:本次就2010年2月至2012年2月我院收治的小脑梗死采用MRI行诊断的患者20例临床资料进行回顾性分析。结果:本组20例患者中,MRI确诊19例,占95%,误诊为小脑胶质瘤1例,后小脑梗死经手术证实。痊愈出院14例,好转出院4例,死亡2例。MRI共检出26个病灶。5例于小脑半球蚓部、15例于单或双侧小脑半球呈类圆形、不规则形异常信号影。所有T2WI病灶均存在程度不等的高信号。T1、T2时间在病程长时表现越长,越有清晰的病灶边界。1例因有环状强化(直径为2cm)征象在注入Gd-DTPA后出现,而诊断为小脑胶质瘤而误诊。结论:小脑及周围组织结构的解剖形态MRI检查可较清楚的显示,可行冠状及矢状成像,三维空间定位能力较理想,在早期小脑梗死的诊断中具有重要的应用价值,减少了误诊率的发生,显著提高了诊断水平。
Objective: To investigate the clinical value of magnetic resonance imaging in diagnosis of cerebellar infarction. Methods: The clinical data of 20 patients diagnosed as cerebellar infarction in our hospital from February 2010 to February 2012 in our hospital were analyzed retrospectively. Results: Among the 20 patients in this group, MRI confirmed 19 cases (95%), misdiagnosed as cerebellar glioma (1) and post-cerebellar infarction confirmed by surgery. 14 cases were discharged, 4 cases were discharged and 2 cases died. MRI detected a total of 26 lesions. 5 cases in the cerebellar hemisphere vermis, 15 cases of single or bilateral cerebellar hemispheres were round, irregular shaped abnormal signal. All T2WI lesions have varying degrees of high signal. T1, T2 time longer performance in the longer performance, the more clear boundaries of the lesion. One patient was diagnosed with cerebellar glioma and was misdiagnosed because of signs of annular enhancement (2 cm in diameter) after Gd-DTPA injection. Conclusion: The anatomy of the cerebellum and the surrounding tissue MRI examination can be more clearly demonstrated that feasible coronary and sagittal imaging, three-dimensional spatial positioning ability is ideal, in the diagnosis of early cerebellar infarction has an important value, reducing the misdiagnosis rate Occurred, significantly increased the level of diagnosis.
