What is corpus callosum infarct?
What is corpus callosum infarct?
In conclusion, the corpus callosum infarction is lack of typical symptoms and signs because it often occurs with other cerebral ischemic lesion. It is reminded of callosal infarction when the patient has consciousness or cognitive change, apraxia, such as alien hand syndrome with mild paralysis.
What does damage to the corpus callosum cause?
Lesions of any part of the corpus callosum might lead to loss of contact between bilateral hemispheres that cause mental disorders, pseudobulbar palsy, speech and movement ataxia.
Does the corpus callosum affect memory?
These studies suggest that the corpus callosum may play a role in the facilitation of different memory functions; however since commissurotomy involves transsection of all cerebral commissures, including the hippocampal commissure, it does not specifically isolate the impact of callosal disconnection (Clark & Geffen.
Are there lesions in the splenium of the corpus callosum?
Abstract 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. We performed this study to clarify the clinical and radiological implications in patients with SCC lesions.
What causes high signal intensity in the corpus callosum?
Histologic examination of the splenium in one autopsy case with a history of chest and neck radiation therapy demonstrated isomorphic gliosis. CONCLUSION: High signal intensity in the splenium of the corpus callosum on FLAIR images is a common finding after brain radiation therapy and can be seen with aging.
Which is most susceptible to an ischemic corpus callosum lesion?
The most susceptible location of ischemic corpus callosum lesion was the splenium. Splenium infarctions were often associated with bilateral cerebral hemisphere involvement (46.2%). The genu and/or body infarctions were associated with atherosclerosis.
What are the risk factors for corpus callosum infarction?
The patients presenting with corpus callosum infarctions were selected and further allocated into genu and/or body and splenium infarction groups. Proportion, lesion patterns, clinical features, risk factors and etiology of corpus callosum infarction were analyzed.
