In a recent analysis (Susac et al., 2003), MRI images from 27 patients fulfilling the diagnostic criteria of Susac's syndrome were reviewed. Multifocal supratentorial lesions were present in all patients. Most lesions were small (3 to 7 mm), though some were larger than 7 mm. All 27 patients had corpus callosum lesions. These all had a punched ...
Dejerine in 1892 described specific symptoms resulting from a lesion to the corpus callosum that caused alexia without agraphia. The patient had a lesion in the left occipital lobe, blocking sight in the right visual field , and in the splenium of the corpus callosum. Dejerine interpreted this case as a disconnection of the speech area in the ...
An MRI study found that the midsagittal corpus callosum cross-sectional area is, after controlling for brain size, on average, proportionately larger in females. [ 15 ] Using diffusion tensor sequences on MRI machines, the rate at which molecules diffuse in and out of a specific area of tissue, anisotropy can be measured and used as an indirect ...
Spastic tetraplegia, thin corpus callosum, and progressive microcephaly (often referred to by its acronym SPATCCM) is a rare autosomal recessive disease caused by mutations in the SLC1A4 gene encoding the ASCT1 protein.
MRI anomalies are not due to substance abuse, such as recreational drug use, toxic exposure, or a prior known medical condition. Exclusion of a differential diagnosis of leukoaraiosis, or extensive white matter pathology excluding the corpus callosum. MRI anomalies of the CNS are not accounted for by another disease.
MBD can be told apart from other neural diseases due to the symmetry of the lesions in the corpus callosum as well as the fact that these lesions don't affect the upper and lower edges. [4] There are two clinical subtypes of MBD. In Type A, stupor and coma predominate. Radiological imaging shows involvement of the entire corpus callosum.
Magnetic resonance imaging (MRI) reveals that deviations in the brain may occur in individuals with Pitt-Hopkins. These can include a small corpus callosum, wide ventricles, and deviations in the posterior fossa. Many individuals with Pitt Hopkins can also have typical brain structures. [14] Musculoskeletal.
Diffuse injury has more microscopic injury than macroscopic injury and is difficult to detect with CT and MRI, but its presence can be inferred when small bleeds are visible in the corpus callosum or the cerebral cortex. [34] MRI is more useful than CT for detecting characteristics of diffuse axonal injury in the subacute and chronic time ...
