(A) Representative photomicrographs: (a) score 0, no expansion; (b) score 1, no cumulus cell expansion but cells appear as spherical; (c) score 2, only the outermost layers of cumulus cells have expanded; (d) score 3, all cell layers have expanded except the corona radiata
; (e) score 4, expansion has occurred in all cell layers including the corona radiata
Caption: FIGURE 1: Axial contrast enhanced T1WI brain MRI demonstrating rim enhancing lesions in the right peritrigonal white matter and left corona radiata
Caption: Figure 1: Brain MRI showing left corona radiata
and parietal ischemic lesion on T2-weighted MRI (a, c) and diffusion-weighted imaging (DWI, (b), (d)).
Caption: Figure 3: Brain MRI performed on the third day revealed (a) high signal intensity on DW image and (b, c) well-defined rounded cystic lesion on the T2-weighted and T1-weighted images involving in the right corona radiata
and basal ganglia, compressing the right lateral ventricle with midline shift to left, suggestive of an early stage of brain abscess.
Decreased levels of NAA in the regions like centrum semiovale, corona radiata
, grey matter and WM suggest neuronal dysfunction.
Particularly, a somatotopic organization of motor fibers in corona radiata
and rostral pons is relatively well known.
Even in the absence of stroke-like episodes, MRI of patient 1 showed widespread hyperintensity on T2-weighted images of the bilateral frontal lobe, bilateral parietal lobe, basal ganglia, and corona radiata
, indicating cerebral ischaemia, lacunar infarction, and cerebral atrophy.
Legends: Primary oocytes (PO), primordial follicles cells (PFH), Epithelial cells (E), tunica albuginea (TA), theca interna (TI), theca eksterna (TE), zona pellucida (ZP), antrum (A), granuloza cells (GH), Secondary oocytes (PO), corona radiata
(CR), cumulus oophorus (CO).
The other 4patients of Behcet's disease presenting with headache, 2 (50%) had normal MRI, 1 (25%) brainstem hyperintensities and 1 (25%) ischemic changes in left insular cortex and corona radiata
. Byung-Sik Cho et al found that the brainstem is the most commonly involved region (55%) in neuro-behcet19.
A non-contrast CT scan of the head reveals foci of low attenuation in the left frontal corona radiata
. Follow-up MRI of the brain, with and without contrast, shows extensive supratentorial and infratentorial demyelinating lesions consistent with multiple sclerosis (MS).
The overlapping lesions of the brain included the putamen, thalamus, internal capsule, corona radiata
, and primary and premotor cortices (Figure 1: the color represents the frequency of overlap).
CT features in early infantile Krabbe disease are increased attenuation in cerebellum, brainstem, thalami, caudate nuclei and corona radiata
on non-contrast CT.
The ROIs were placed bilaterally (except for the corpus callosum) at the following anatomical locations: the posterior limb of the internal capsule, the centrum semiovale anterior, the posterior corona radiata
anterior and posterior, the splenium and the genu of the corpus callosum, the thalamus, and the caudate nucleus (Figure 1).
