A perivascular space, also known as a Virchow–Robin space, is a fluid-filled space surrounding certain blood vessels in several organs, potentially having an immunological function, but more broadly a dispersive role for neural and blood-derived messengers. The brain pia mater is reflected from the surface of the brain onto the surface of blood vessels in the subarachnoid space. In the brain, . In brief: Normal. Perivascular (also known as perivenular or virchow-robin) spaces can be seen at any age and have bizarre or asymmetric configurations. They tend to become more numerous and larger as a person ages, and are benign. The only concern is if they are confused for a cystic space .

There are six types of vascular malformations of the brain: telangiectasis, venous malformations, cavernous malformations, arteriovenous malformations, vein of Galen malformation and mixed malformations. Dilated Perivascular Spaces in Identifying Mild Brain Injury. Dilated Perivascular Spaces are also called Virchow Robbin Spaces. In essence, Dilated Perivascular Spaces are areas surrounding blood vessels in the brain, where myelin sheath or other brain tissue is Author: Braininjurylawgroup.

Perivascular spaces are interstitial fluid filled spaces that line perforating vessels of the basal ganglia. They are located in the pial layer of the brain. They are typically less than 5 millimeters in size, and are increasingly visualized on MRI with better technology and imaging resolution. The average adult produces about one pint of CSF daily. When an injury or illness alters the circulation of CSF, one or more of the ventricles becomes enlarged as CSF accumulates. In an adult, the skull is rigid and cannot expand, so the pressure in the brain may increase profoundly. Hydrocephalus is a .
