Clinical Course Internal border zone infarcts are associated with a poor prognosis and clinical deterioration ( 21 , 22 ). 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). 12 Centrum Semiovale. A, Color-coded DTI axial map at the level of the centrum semiovale, which is defined as the common central mass of white matter with an oval appearance in horizontal sections of the brain. From lateral to medial, the superior longitudinal fasciculus (anteroposterior orientation, green), corona radiata (craniocaudal orientation, blue), and cingulum (anteroposterior 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.

This case serves to illustrate that stroke can mimic a sacral radiculopathy. In the present report, we discuss the case of a 66-year-old woman with isolated unilateral hypoglossal paralysis due to cerebral infarction in the centrum semiovale. To date, it has hardly been discussed where the corticolingual tract passes through in the centrum semiovale.

Look for restricted diffusion in the centrum semiovale on MRI. Treat the patient with dextromethorphan or aminophylline. McGovern Medical School Symptoms and signs of internal capsule stroke include weakness of the face, arm, and/or leg (pure motor stroke). Pure motor stroke caused by an infarct in the internal capsule is the most common lacunar syndrome.

The presence of these cortical signs may exclude an internal capsule stroke: gaze preference or gaze deviation. expressive or receptive aphasia. visual field deficits. visual or spatial neglect. If any of these signs are present, the patient may have a cortical stroke, not an internal capsule stroke.

This area is nourished by small penetrating arteries, so lacunar infarcts are relatively common here.

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). 12 The presence of these cortical signs may exclude an internal capsule stroke: gaze preference or gaze deviation. expressive or receptive aphasia. visual field deficits.

Herein, we present a 58-year-old male patient presenting with isolated psychotic depression which was finally found to be associated with acute ischemic stroke of bilateral centrum semiovale. This report constitutes an extremely rare illustration of acute onset organic psychotic depression which was clearly demonstrated to be associated with ischemic stroke.

This case serves to illustrate that stroke can mimic a sacral radiculopathy. The presence of these cortical signs may exclude an internal capsule stroke: gaze preference or gaze deviation. expressive or receptive aphasia. visual field deficits. visual or spatial neglect. If any of these signs are present, the patient may have a cortical stroke, not an internal capsule stroke.

MR imaging of the brain revealed an acute infarct (demonstrated by multiple foci of abnormal signal intensity in the white matter of the centrum semiovale. initial episode of neurologic deficit and 3 months after diagnosis of APMP

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.
