What is the Virchow-Robin space?

Virchow–Robin spaces (VRS) are brain perivascular spaces containing perforating arteries. Although enlarged VRS are associated with various disorders such as Alzheimer’s disease, cerebrovascular disease, and head trauma, their functional role remains unclear.

What causes Virchow-Robin spaces?

[6] Large Virchow-Robin spaces (VRS) have been associated with age, dementia, multiple sclerosis, trauma, hypertension, and incidental white matter lesions.

What is meant by perivascular spaces?

Perivascular spaces are fluid-filled spaces that follow a typical course of a vessel penetrating/transversing the brain through gray or white matter.

Are prominent perivascular spaces normal?

Perivascular spaces are normal anatomical structures. Even when enlarged they are almost invariably asymptomatic, even when quite large. Rarely, they can cause mass-effect and can result in obstructive hydrocephalus.

What is white matter hyperintensities?

Abstract. White matter hyperintensities (WMHs) are brain white matter lesions that are hyperintense on fluid attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) scans. Larger WMH volumes have been associated with Alzheimer’s disease (AD) and with cognitive decline.

What is periventricular space?

A perivascular space, also known as a Virchow–Robin space, is a fluid-filled space surrounding certain blood vessels in several organs, including the brain, potentially having an immunological function, but more broadly a dispersive role for neural and blood-derived messengers.

What causes perivascular spaces in brain?

The exact causes of EPVS are uncertain but the perivascular space is an important conduit for drainage of interstitial fluid to the ventricles17 and could be affected by various factors, including abnormalities at the blood brain interface and inflammation.

Where are perivascular spaces located?

Perivascular spaces are most commonly located in the basal ganglia and white matter of the cerebrum, and along the optic tract. The ideal method used to visualize perivascular spaces is T2-weighted MRI. The MR images of other neurological disorders can be similar to those of the dilated spaces.

What is prominent perivascular spaces in basal ganglia?

Abstract. Enlarged perivascular spaces (EPVS) are a feature of cerebral small vessel disease (cSVD) and have been related to cSVD severity. A higher number of EPVS were related to decreased cognition in healthy elderly, but this has never been investigated in patients at high risk of cSVD.

Is white matter on brain serious?

Some white matter lesions may not cause noticeable symptoms and can be considered almost “normal” with aging. However, some of these lesions can damage important pathways (highways) within your brain and can cause problems with memory, balance and walking.

Can white matter lesions in the brain be nothing?

Studies have found that white matter lesions appear in some degree on brain scans of most older adults but less often in younger people. White matter lesions are among the most common incidental findings—which means the lesions have no clinical significance—on brain scans of people of any age.

What causes perivascular spaces?

What fluid is in the perivascular space?

Perivascular spaces are gaps containing interstitial fluid that span between blood vessels and their host organ, such as the brain, which they penetrate and serve as extravascular channels through which solutes can pass.

What kind of doctor treats white matter disease?

Healthcare providers such as neurologists and neuro-radiologists are often able to distinguish white matter disease lesions from other causes of lesions with MRI based on where they’re located in your brain. Sometimes additional testing is necessary to help determine the cause of the white matter lesions on your MRI.

Can stress cause white matter lesions?

Increased exposures to stressful events are associated with a corresponding increase in the progression of white matter hyperintensities.

What are CSF spaces in the brain?

Cerebrospinal fluid CSF is a clear, watery fluid that fills the ventricles of the brain and the subarachnoid space around the brain and spinal cord. CSF is primarily produced by the choroid plexus of the ventricles (≤70% of the volume); most of it is formed by the choroid plexus of the lateral ventricles.

What is the life expectancy of someone with white matter disease?

Within 2 years, children can develop gait and posture problems, as well as blindness and paralysis. It is not possible to stop disease progression, and it is typically fatal within 6 months to 4 years of symptom onset.

Can you live a normal life with white matter disease?

The life expectancy after a diagnosis of white matter disease depends on the speed it progresses and the severity of any other conditions it may cause, like stroke and dementia. White matter disease is believed to be a factor in both strokes and dementia. However, more research must be done for further confirmation.

What is the difference between VR spaces and lacunar infarctions?

In contrast to VR spaces, lacunar infarctions are generally not symmetric (, 30,, 32,, 33,, 50 ). It is difficult to distinguish lacunar infarctions from VR spaces by means of shape. However, wedge-shaped holes are more likely to be lacunar infarctions (, 50 ).

How is chronic lacunar infarct differentiated from perivascular space?

A chronic lacunar infarct may be difficult to distinguish from a perivascular space. It may be cystic with CSF density and intensity on CT and MRI, respectively. It may be isointense to mildly hypointense on T1WI if not cystic. If the lacuna is close to the ventricular system, it may cause focal ex-vacuo dilatation of the ventricle.

Are wedge-shaped holes more likely to be VR spaces or lacunar infarctions?

However, wedge-shaped holes are more likely to be lacunar infarctions (, 50 ). Lacunar infarctions can be differentiated from VR spaces by signal intensity characteristics.

Virchow-Robin spaces are named after German pathologist Rudolf Virchow (1821–1902) 15 and French anatomist Charles-Philippe Robin (1821–1885) who described them further in 1851 and 859 respectively 16,20. Interestingly Virchow and Robin disagreed on whether or not these spaces directly communicated with the subarachnoid space.
