Spontaneous Regression and Recurrence of a Tumefactive Perivascular Space [PDF]
Neuroradiology Journal, 2014 Perivascular spaces can occasionally appear mass-like (tumefactive or giant perivascular space), and can be associated with clinical symptoms. Spontaneous regression of a tumefactive perivascular space is a very rare phenomenon with only two reported ...

Arterial Pulsation-driven Cerebrospinal Fluid Flow in the Perivascular Space: A Computational Model [PDF]
Computer Methods in Biomechanics and Biomedical Engineering, 2003 This study was conducted to determine whether local arterial pulsations are sufficient to cause cerebrospinal fluid (CSF) flow along perivascular spaces (PVS) within the spinal cord.

The glymphatic system is hypothesized to act as the brain's filtration system to remove toxic solutes that accumulate throughout the day. Perivascular spaces (PVSs) play a fundamental role in the ability of the glymphatic system to function, and sleep influences the effectiveness of this system.

Evaluation of glymphatic system activity with the diffusion MR technique: diffusion tensor image analysis along the perivascular space (DTI-ALPS) in Alzheimer’s disease cases [PDF]
Japanese Journal of Radiology, 2017 Purpose: The activity of the glymphatic system is impaired in animal models of Alzheimer’s disease (AD). We evaluated the activity of the human glymphatic system in cases of AD with a diffusion-based technique called diffusion tensor image analysis along

MRI-visible perivascular space location is associated with Alzheimer's disease independently of amyloid burden [PDF]
Brain, 2017 Perivascular spaces that are visible on magnetic resonance imaging (MRI) are a neuroimaging marker of cerebral small vessel disease. Their location may relate to the type of underlying small vessel pathology: those in the white matter centrum semi-ovale ...

Perivascular spaces and their role in neuroinflammation
Neuron, 2022It is uncontested that perivascular spaces play critical roles in maintaining homeostasis and priming neuroinflammation. However, despite more than a century of intense research on perivascular spaces, many open questions remain about the anatomical compartment surrounding blood vessels within the CNS.

Giant tumefactive perivascular spaces
Journal of the Neurological Sciences, 2008We describe the imaging characteristics of giant tumefactive perivascular spaces in a 37-year-old man who initially presented at the age of twenty years with vision change and headache and was found to have probable low grade neoplasm. The patient was followed subsequently at 8 years and 17 years later at our institution with stable imaging and ...
