Virchow-Robin spaces (VRS) are extensions of the subarachnoid space surrounding perforating blood vessels entering the brain parenchyma. VRS are fluid filled, but almost virtual and only visible on MRI of the brain when dilated. Such dilations are commonly asymptomatic. In rare cases, extreme dilations can be observed; the clinical repercussions of which remain unclear. We report the case of a patient presenting symptoms of normal pressure hydrocephalus due to extreme VRS mesencephalon dilations.
魏尔啸-罗宾间隙(VRS)是蛛网膜下腔的延伸,围绕进入脑实质的穿支血管。VRS内充满液体,但几乎是虚拟的,只有在扩张时在脑部MRI上才能看到。这种扩张通常无症状。在罕见情况下,可观察到极度扩张;其临床影响尚不清楚。我们报告了一例因VRS中脑极度扩张而出现正常压力脑积水症状的患者。
