Intermittent XXXX caused by a dilated Virchow-Robin space close to the optic radiation: Therapeutic and pathomechanical considerations.

@entity1 @entity51 @entity227 @entity73
OBJECTIVE: Virchow-Robin spaces (VRSs) are extensions of subarachnoid spaces that accompany vessels entering the brain. T2-weighted magnetic resonance imaging detects VRS in about 95 percent of @entity1 in a recent study. VRSs are considered a normal variant with benign prognosis. (1) Occasionally, VRS might become symptomatic causing @entity51 depending on their location. (2) Case description. We report the case of a 55-year-old female @entity1 with dilated VRS presenting with @entity227 and @entity73 . The @entity1 underwent endoscopic fenestration of a large periventricular VRS located next to the visual radiation into the posterior horn of the right lateral ventricle. During the postoperative course, @entity227 were resolved but @entity73 remained unchanged. CONCLUSION: Dilated VRSs can cause a variety of @entity51 depending on their size and location. Therefore, @entity1 harboring dilated VRS should undergo early close inspection and in case of progressive @entity51 , an operative therapy should be done; as valve mechanisms can cause a reduction of size when brain scans are conducted and later lead to occurrence of severe @entity51 during phase of dilation.
