White Matter Disease: What It Is, Symptoms & Treatment - Cleveland Clinic
White matter changes are visible on magnetic resonance imaging (MRI) as lesions. An MRI report can call white matter changes a few different things, including: Cerebral or subcortical white matter disease or lesions. Microvascular disease. Non-specific white matter changes. T2 hyperintensities (lesions).
What are White Matter Lesions, and When Are They a Problem?
Abnormalities in white matter, known as lesions, are most often seen as bright areas or spots on MRI scans of the brain. Very often the lesions themselves don't cause any noticeable problems. But sometimes they may indicate significant damage to white matter that can disrupt neuronal (nerve signal) transmission and interfere with the way the ...

The clinical importance of white matter hyperintensities on …
Nov 23, 2009 · White matter lesions are considered present if hyperintense on T2 weighted, fluid attenuated inversion recovery, and proton density images, without prominent hypointensity on T1 weighted images. Several studies have assessed the relation between white matter hyperintensities and risk of stroke, dementia, and death, with partly conflicting results.
Subcortical U-fibers involvement in white matter disorders
It is important to recognize the distinction between superficial white matter lesion locations: juxtacortical - directly abuts the cortex (and involving the U fibers); subcortical – has an intervening layer of white matter between the lesion and the …
Chapter 14: White Matter Abnormalities - Neurology
Subcortical white matter hyperintensities in periventricular regions and diffuse spinal cord atrophy are notable on neuroimaging, resulting clinically in gait disturbance and hyperreflexia. CARASIL is caused by a novel homozygous splice site mutation and can include clinical and imaging findings consistent with cervical myelopathy.
Adult Leukodystrophies: A Step-by-Step Diagnostic Approach
White matter lesions appear as hyperintensity on T2-weighted and FLAIR MR images and hypo- or isointensity on T1-weighted images. Depending on the cause and stage of the disease, signal intensity may vary.
