Lesions extending up to the subcortical region. Posterior white matter: No lesion. Lesions partly involving the white matter.

Constitutes the majority of the brain volume, and is divided into zones (subcortical, periventricular and subependymal) and larger named bundles including association fibers which connect one cortical area to another within a hemisphere (e.g., cingulum, arcuate fasciculus), commissural fibers which connect the cortices of two hemispheres ...

The numbers of periventricular (P = 0.05), cortical/subcortical (P = 0.02) and discrete (P = 0.05) lesions detected using fast-FLAIR were higher than those detected using CSE. The data indicates that fast-FLAIR sequences are more sensitive than CSE in detecting multiple sclerosis lesion burden and that fast-FLAIR is a promising technique for ...

Lesions are usually bilateral, asymmetric, and localized preferentially to the periventricular areas and the subcortical white matter [1]. Involvement of the deep gray structures, including basal ganglia and thalamus, can nevertheless be found in up to 17 percent of cases.

Lesions are multifocal in 40% and are usually subcortical. Most common presenting si/sx are cognitive and behavioral changes, but hemiparesis, aphasia, or seizures MRI shows periventricular lesion w/ diffuse and homogenous enhancement. Stereotactic biopsy usually required for definitive diagnosis. LP b/c can disseminate to CSF in 25%

Brain lesions on MRI, including number of lacunes and periventricular hyperintense lesions, were compared among 15 age- and sex-matched control subjects with postural hypotension, 15 with postural hypertension, and 30 with postural normotension. RESULTS: Twenty subjects (6.0%) exhibited postural hypotension and 29 (8.7%) postural hypertension.
