68) In 1 study, MRI findings which favored recurrent tumor included involvement of the corpus callosum with subependymal spread, corpus callosal
involvement with crossing of the midline and multifocal lesions, and the combination of corpus callosal
involvement with subependymal spread and multiple lesions.
Because a firm diagnosis of a callosal
disorder has only been possible since the advent of neuroimaging, this range of conditions is only beginning to be understood.
Significant differences in area were found between the groups in the callosal
subregion that included the isthmus and splenium.
connections correlate preferentially with ipsilateral cortical domains in cat areas 17 and 18, and with contralateral domains in the 17/18 transition zone.
MRI works particularly well in identifying ventriculomegaly, lesions within the posterior fossa, callosal
anomalies and abnormalities in cerebral myelination, migration, and sulcation, Dr.
surgery, the left hemisphere retains all its former ability to discern causal connections in testing situations, such as knowing that "bleed" is an appropriate follow-up to "pin" and "finger.

In acute MBD, MRI reveals focal callosal
lesions of high T2-weight and FLAIR signals with hypoattenuation and low T1-weight signals.
The pattern of callosal
thinning showed a similar graded effect.
