What is etat Crible?

État criblé, also known as status cribrosum, is a term that describes the diffusely widened perivascular spaces (Virchow-Robin spaces) in the basal ganglia, especially in the corpus striatum on MRI. It is usually symmetrical, with the perivascular spaces showing CSF signal and without diffusion restriction.

What causes Virchow-Robin space?

[3,4,5] Extreme unilateral dilation of Virchow-Robin spaces may also be encountered. [6] Large Virchow-Robin spaces (VRS) have been associated with age, dementia, multiple sclerosis, trauma, hypertension, and incidental white matter lesions.

Can white matter Hyperigtensities be benign?

While these associations exist, WMH are usually benign depending on the location and how extensive the lesions are. Benign WMH are found in >90% of people over the age of 60. Larger or more extensive WMH can be seen in cerebrovascular disease, infection, neurodegenerative conditions or multiple sclerosis.

Where are the basal ganglia?

The term basal ganglia in the strictest sense refers to nuclei embedded deep in the brain hemispheres (striatum or caudate-putamen and globus pallidus), whereas related nuclei consist of structures located in the diencephalon (subthalamic nucleus), mesencephalon (substantia nigra), and pons (pedunculopontine nucleus).

What is a perivascular space?

Perivascular spaces (PVSs), also known as Virchow-Robin spaces, are pial-lined, fluid-filled structures found in characteristic locations throughout the brain. They can become abnormally enlarged or dilated and in rare cases can cause hydrocephalus.

Where are perivascular spaces?

Perivascular spaces, also known as Virchow-Robin spaces are fluid-filled spaces that surround small arterioles, capillaries and venules in the brain. Those that surround perforating vessels are frequently seen on routine MRI imaging.

What are perivascular spaces in basal ganglia?

Perivascular spaces (PVS) are interstitial fluid-filled cavities surrounding small perforating vessels in the brain.

What kind of doctor treats white matter disease?

A neuroradiologist is a doctor who is certified in general radiology and has also undergone specialty training, often with an added board certification in imaging of the brain, spine, and nerves. With this training, they’re able to recognize both common and uncommon disorders that affect the nervous system.

Are white matter lesions serious?

Serious consequences of periventricular white matter lesions — this is the scary part. There is strong evidence that cerebral white matter lesions impair brain function, and in particular impair thinking ability and walking.

When does bleeding occur at the level of the basal ganglia?

When a bleeding occurs at the level of the basal ganglia, this means that the area of the brain that is responsible for the movements of the body, sensation, speech and personality has suffered. The basal ganglia hemorrhage is one of the most frequent hemorrhages that occur at the level of the brain.

What happens if you have a basal ganglia stroke?

A basal ganglia stroke could have lasting effects that may interfere with your quality of life. Having any type of stroke increases your risk of having another stroke. Having a basal ganglia stroke or other damage to that part of the brain may also increase your risk of developing Parkinson’s disease.

When to use CSF for basal ganglia hemorrhage?

If the hemorrhage has occurred, with hydrocephalus being also present at the level of the brain, CSF drainage might be required (along with the extra-ventricular drain). The evacuation of the clot is only recommended only in the large hemorrhages (over 60 ml).
