The centrum semiovale is a mass of white matter superior to the lateral ventricles and corpus callosum, present in each of the cerebral hemispheres , subjacent to the cerebral cortex. It has a semi-oval shape and contains projection, commissural, and association fibers. Inferolaterally these fibers are continuous with the corona radiata.

Conclusions: Isolated monoparesis is a rare symptom in stroke patients and is often caused by small artery disease or a small haemorrhage. The significant poor prognostic indicators (for patients who either deteriorated or died) among patients having stroke were presence of cranial nerve deficit (P = 0.015), internal capsule infarct (P = 0.05), centrum semiovale (P = 0.001) and brainstem (P = 0.00) infarcts. In this retrospective study, a total of 42 patients following dysphasia suffered from stroke mainly in the basal ganglia region and/or the centrum semiovale. The patients who could not undergo VFSS or FEES because of poor consciousness or were unable to perform a 1-step command were excluded.

Pure motor stroke (PMS), also known as pure motor hemiparesis, is the most common of any lacunar form (between one half and two thirds of cases, depending on the series). In an acute stroke registry, 733 patients presented a lacunar infarct and PMS accounted for 12.7% (n = 342) of all first-ever stroke patients and for 48% of all lacunar syndromes.

The centrum semiovale, semioval center or centrum ovale is the central area of white matter found underneath the cerebral cortex. The white matter, located in each hemisphere between the cerebral cortex and nuclei, as a whole has a semioval shape. It consists of cortical projection fibers, association fibers and cortical fibers. In acute/subacute stroke like MTX-induced neurotoxicity, DW and T2 hyperintensities are typically located in the periventricular white matter, particularly in the centrum semiovale, and often seen only on DWI (diffusion weighted images).

In neuroanatomy, the corona radiata is a white matter sheet that continues inferiorly as the internal capsule and superiorly as the centrum semiovale. This sheet of both ascending and descending axons carries most of the neural traffic from and to the cerebral cortex. The corona radiata is associated with the corticopontine tract, the corticobulbar tract, and the corticospinal tract. Basal ganglia and centrum semiovale EPVS were not normally distributed, and so we assessed univariate and multivariate associations with explanatory variables dichotomizing EPVS into 0–1 vs. 2–4, replicating the method used in previous studies. 3,4 In both multivariate models, we included as explanatory variables age, sex, hypertension, diabetes, lacunar stroke (according to TOAST CONCLUSION: The results suggest that WMH may be an important factor to consider in stroke-related upper extremity motor impairment.
