脑内明显扩张的血管周围间隙21例临床分析

Unusual Widening of Virchow-Robin Space in the Brain

目的探讨明显扩张的血管周围间隙的临床及磁共振特征。方法回顾分析21例明显扩张血管周围间隙患者的临床及磁共振影像资料。结果本组患者临床症状以头痛和癫痫较为多见,多合并高血压病及脑血管疾病;明显扩张的血管周围间隙在磁共振上按解剖部位可分为3型:1型血管周围间隙位于基底节,2型位于半卵圆区,3型位于其他部位;在形态学上可归纳为四种形式:单发囊型、局限簇集型、单侧为主的密集囊型以及蜘蛛网型。结论明显扩张的血管周围间隙的磁共振表现有一定的特异性,但其临床表现缺乏特异性,头痛和癫痫与本病的相关性有待进一步探讨。

Aim To explore the feature of MRI and clinical manifestations of unusual widening of Virchow-Robin space in the brain. Methods 21 patients＇ MRI and clinical data were analyzed respectively. Results Headache and epilepsy episodes were common clinical symptom. Moreover most patients were accompanied by hypertension and cerebrovascular disease. Unusual widening of Virchew-Robin spaces on MPd were divided into three types according to anatomic location, type Ⅰ at ganglia, type Ⅱ at semioval centrum, type Ⅲat other location. Unusual dilated Virchow-Robin spaces were classified into four sorts by morphology characteristics, type Ⅰ mono-vesicle, type Ⅱ focal cluster, type Ⅲ dense vesicles mostly located unilaterally, type Ⅳ spider net-llke. Conclusions Unusual widening of Virchow-Robin Spaces in the brain had some characteristic manifestations on MRI. However, its clinical manifestations were lack of characteristic and the relation of headache and epilepsy with unusual dilated Virchow-Robin space still needs further investigation.
