Perivascular or Virchow-Robin spaces (VR) of the brain are fluid-filled, pial-lined spaces that accompany the cerebral vessels as they pass from subarachnoid space into the brain parenchyma. They are visualized on routine MR examinations as CSF intensity spaces and are normally < 2 mm in size. These spaces may rarely enlarge massively and can be mistaken for more ominous pathologic processes on CT scan and even on MRI, but careful examination on special sequences and follow-up examination can clear the uncertainty. We describe a case of a young male who presented with mildly progressive neurological symptoms and the imaging findings were typical of enlarged VR spaces. Patient was advised follow up and is doing well.
脑的血管周围间隙或维-罗间隙（VR）是充满液体、由软脑膜衬里的间隙，当脑血管从蛛网膜下腔进入脑实质时，这些间隙伴随血管走行。在常规磁共振检查中，它们表现为脑脊液信号强度的间隙，大小通常<2mm。这些间隙很少会大量扩大，在CT扫描甚至MRI上可能被误诊为更严重的病理过程，但通过特殊序列的仔细检查和随访检查可以消除不确定性。我们描述了一例年轻男性病例，该患者出现轻度进行性神经症状，影像学表现为典型的维-罗间隙扩大。建议患者进行随访，其目前情况良好。
