The Virchow-Robin spaces (VRS) are subpial invaginations making a tubular revestment scabbard that contains a vase between the subarachnoid and subpial spaces. The magnetic resonance imaging (MRI) is the only imaging method able for evaluate this anatomic detail. We studied the possible association

Virchow-Robin spaces (VRS) are pia-lined extensions of the subarachnoid space which surround penetrating arteries as they enter the brain on its surface. Using high-resolution MRI, which shows small penetrating arteries, we studied a possible association of accentuated VRS in children with

BACKGROUND
Virchow-Robin spaces (VRS) or perivascular spaces are interstitial cystic spaces surrounding the vasculature of brain parenchyma and course from the subarachnoid space. Small VRS (<2 mm) appear in all age groups, but can enlarge and be confused with other lesions like cystic neoplasms.

BACKGROUND
Obstructive hydrocephalus secondary to enlarged Virchow-Robin Spaces (VRS) is a rare entity, with only a few cases reported in the literature. Presenting symptoms vary widely from headaches to dizziness.
METHODS
We report a case of a 31-year-old man who presented with pulsatile tinnitus

BACKGROUND
Virchow Robin spaces (VRSs) are perivascular spaces that act as drainage pathways for interstitial fluid. Dilatation of VRSs is visible on magnetic resonance images in asymptomatic individuals. However, giant dilatation of VRSs (dVRSs) is very rare. Such giant dVRSs may produce a pressure

OBJECTIVE
The distinctive hyperintensity of multiple sclerosis (MS) lesions on T2-weighted brain MR images is well recognized. However, Virchow-Robin spaces (VRSs), especially in early MS, have not been described. Our purpose was to determine the frequency of VRSs in recent-onset MS.

RESULTS
Thirty-seven patients had
[Dilatation of Virchow-Robin perivascular spaces (types III cerebral lacunae): radio-clinical correlations].
Alleen geregistreerde gebruikers kunnen artikelen vertalen
Log in Schrijf in
OBJECTIVE
Virchow-Robin spaces are pia-lined extensions of the subarachnoid space surrounding the path of brain vessels. When enlarged, such dilated perivascular spaces are often seen as foci of cerebrospinal fluid signal on MRI or CT scan. These foci are found in patients with miscellaneous
