The perivascular spaces are normally microscopic. Even in normal brain some Robin-Virchow spaces are usually seen in the area of substantia innominata at the level of anterior commissure. Many pathologic states result in abnormal dilatation with an increased number of spaces visible on MRI imaging. Dilatation is most commonly associated with anterior abnormalities that arise due to aging, diabetes, hypercholesterolemia, smoking, hypertension and other vascular risk factors. The precise etiology of dilatation is currently unknown.
血管周围间隙通常是微观的。即使在正常大脑中，在前连合水平的无名质区域通常也能看到一些鲁宾-菲尔绍间隙。许多病理状态会导致异常扩张，在MRI成像上可见的间隙数量增加。扩张最常与因衰老、糖尿病、高胆固醇血症、吸烟、高血压和其他血管危险因素引起的前部异常有关。目前尚不清楚扩张的确切病因。
