Our result emphasizes the importance of the internal capsule and corona radiata in motor function in patients with stroke.
Compared to controls, increased ADC values were detected in 6/8 regions in SPMS (internal capsule, corona radiata anterior and posterior, centrum semiovale, and splenium and genu of the corpus callosum), 4/8 regions in both RRMS or PPMS (internal capsule, corona radiata anterior and posterior, and centrum semiovale), and 2/8 regions (internal capsule and centrum semiovale) in CIS Figure 2(a)).
On investigations magnetic resonance imaging (MRI) of the brain (Figure 1) showed an acute nonhemorrhagic right middle cerebral artery (MCA) territory infarct with the putamen extending to the corona radiata. There was no significant narrowing in the arteries of the circle of Willis.
The centrum semiovale and posterior PVWM contain the corona radiata, which includes fibers originating in the motor cortex that continue ventrally to comprise the posterior limb of the internal capsule.
At this stage the egg is surrounded by a cloud of cells brought with it from the ovary, poetically named the corona radiata. While travelling along the tube, if the egg does not encounter sperm it quickly dies and the menstrual cycle continues towards the eventual expulsion of the lining of the womb.
In this article, our aim was to present a patient who was admitted with hyperglycemia and hemichorea and who had hyperdense appearance on cranial computed tomography (CT) scan and ipsilateral acute infarction of the corona radiata. We discuss the relationship between hyperglycemia, ischemic stroke, and hemichorea in light of the literature.
Additional foci of hyperintense signal were seen within the right and left periatrial white matter as well as within the bilateral corona radiata and centrum semiovale.
Fifteen months after onset, a 24-h electroencephalography (EEG) was unremarkable, and brain MRI showed atrophy in the right insular cortex, caudate, putamen, and cerebral crus with high signals in the corona radiata on T2-weighted and fluid-attenuated inversion recovery images.
8: Axial T2WI at the level of corona radiata shows the diffuse involvement of the cortical white matter.
