Left frontal centrum semiovale stroke
What is yellow centrum semiovale?
Yellow – centrum semiovale are supraventricular white matter tracts running to and from the cerebral cortex Blue – parietal lobe Anatomy – vertex or top of the Brain Anatomy
Are CSO infarcts more sensitive to hemodynamic failure?
However, CSO infarcts clearly seem more sensitive to hemo- dynamic failure.37,74–76Thus, despite their small size, CSO infarcts represent the “tip of the iceberg” of decreased perfusion reserve, and as such may predict impending cortical stroke.
Does cerebral blood flow reactivity predict stroke in symptomatic carotid artery occlusive disease?
Webster MW, Makaroun MS, Steed DL, Smith HA, Johnson DW, Yonas H. Compromised cerebral blood flow reactivity is a predictor of stroke in patients with symptomatic carotid artery occlusive disease. J Vasc Surg. 1995;21:338–344; discussion 344–335. 89. Gur AY, Bova I, Bornstein NM.
Can microemboli propagate to a cortical border zone infarct?
As opposed to internal border zone infarcts, microembolifrom the heart or atheroembolicevents can propagate to the cortical border zones; these areas have a lower perfusion than more proximal regions, so less ability to “wash out” the microemboli Recent intraplaquehemorrhage/plaque rupture may play a role

so-called rosary-like pattern in the centrum semiovale. However, the relationships between cortical WS infarction and hemodynamic compromise appear more complicated. Thus, although severe hemodynamic compromise appears to underlie combined cortical and internal WS infarction, artery-to-artery embolism may play an important role in isolated ...

ond practical issue is that a hemorrhagic lesion in the centrum semiovale can seem a long distance from the outer surface of the brain and still be quite close to the corticosubcortical junction (Figure 1D) because of the undulating curves of the cortical gyri. Hemorrhages are considered deep hemispheric

Recurrence was evi- dent by 217 lacunes in the 88 patients, an average of more than 2 lesions per person. The author observed that lesions involving the internal capsule arose primarily in gray masses
