Corpus callosum is Latin for “tough body,” and the corpus callosum is the largest connective pathway in the brain, being made up of more than 200 million nerve fibers. Very occasionally, a

Lesions of the splenium of the corpus callosum are usually seen in association The ovoid splenium lesion seen in our patient was likely ischemic in nature as

2021-02-21 · Fig. 3. 64-year-old male patient with curvilinear type pericallosal lipoma and partial corpus callosal agenesis. T1-weighted axial (A) and sagittal (B) images show hyperintense lipoma (arrows) superior and posterior to corpus callosum. Splenial portion is not fully developed. - "Splenial Lesions of the Corpus Callosum: Disease Spectrum and MRI Findings" Corpus callosum lesions have a broad differential diagnosis, with the greatest concern for a neoplasm in an elderly patient. The most common tumors affecting the corpus callosum are glioblastoma multi-forme (GBM) and lymphoma. GBM spreads by direct extension along white matter tracts, and may grow through the corpus cal- Abstract.

With other infectious diseases, the involvement of the corpus callosum is typically transitory; however, in the setting of COVID-19, this has yet to be determined. 6, 16 The patient also had ischemic changes in other parts of the brain, and an alternative consideration is a stroke of the corpus callosum. We hypothesized that lesions in the corpus callosum (CC), because of their strategic location, are associated with widespread reductions in microstructural white matter integrity and worse cognitive performance, specifically in the domains of attention/information processing speed and executive functioning. The patient had multiple vascular risk factors and Lambl excrescence, which could be the cause of the ischemic stroke independent of the corpus callosum lesion. It has been hypothesized that a GBM can lead to ischemia by causing a procoagulant state or by compression of cerebral arteries by tumor. Summary: Infarcts of the corpus callosum have not been well documented in the radiologic literature. We present five cases that were unusual in either their clinical or radiologic presentation or both.

Clinically, they are associated with neuropsychiatric symptoms, mainly interhemispheric disconnection syndromes. Background: Brain MRI may unexpectedly display abnormalities in splenium of the corpus callosum (SCC). However, the clinical implications of this lesion are unclear and are not always consistent with ischemic infarctions.

Neonatal images of 34 infants were reviewed. Ten of Transient Lesion of the Splenium of the Corpus Callosum after Acute Ischemic Stroke: A Report of Two Cases YoshitakaYamaguchi 1,2 , YukoIwasaki 2 ,ManabuWada 1 ,NaokiMakita 2 ,HikaruNagasawa 1 , Sometimes, the lesion spreads throughout the whole corpus callosum and into the adjacent white matter without additional lesions, disappearing within approximately two weeks with neither residual signal changes on MRI nor atrophy (Hoshino et al., 2012; Tada et al., 2004; Takanashi et al., 2006). Proportion, lesion patterns, clinical features, risk factors and etiology of corpus callosum infarction were analyzed. RESULTS: Out of 1,629 cases, 59 patients (3.6%) with corpus callosum infarctions were identified by diffusion weighted imaging, including 7 patients who had ischemic lesions restricted to the corpus callosum territory. 2001-09-01 · The pathological features of the MBD consist of acute or subacute symmetrical demyelination of the middle portion of the corpus callosum with or without necrosis.

Spreading of the lesion to the neighboring hemispheric white matter is not rare. In vivo diagnosis was rarely established before the advent of the CT and MR. ObjectivesThe aim of this study was to investigate patients with ischemic infarctions in the territory of the corpus callosum to advance our understanding No lesions involving other limbic system structures such as thalamus, fornix, corpus callosum, or hippocampal structures were seen.

With other infectious diseases, the involvement of the corpus callosum is typically transitory; however, in the setting of COVID-19, this has yet to be determined. 6, 16 The patient also had ischemic changes in other parts of the brain, and an alternative consideration is a stroke of the corpus callosum.

Lesions of the splenium of the corpus callosum after hypoxia are bilateral and lead to poor prognosis. The corticospinal tract and corpus callosum may be involved in these pathways. DWI and ADC maps often depict acute or subacute ischemic lesions in the corpus callosum, internal capsule and white matter when conventional MRI and CT are normal or only show subtle abnormalities (Figure 4) (12).

Cytotoxic lesions of the corpus callosum were classified into 2 types: a small type localized in the splenium in 26 cases (78.9%) and a large type spread along the ventricle in 7 cases (21.2%). The severity of SAH, coiling, hydrocephalus, and poor mRS score at discharge were significantly higher in the group with cytotoxic lesions of the corpus callosum.

Nine of the 13 neonates with normal DWI lesions of the callosum are uncommon and midline ischemic lesions are rare [1-3].
