Background
Corpus callosum is one of the three interhemispheric commissures (anterior commissure,
hippocampal commissure and corpus callosum) and the greatest of them.
[1].
Its role is interhemispheric connection and coordination,
as well as cognitive functions,
social skills,
problem solving and attention.
[2]
Corpus callosum development is a very quick process and takes place in 13th week of gestational life.
In its embryological development,
corpus callosum is formed by two separate parts: the anterior one,
consisting of the rostrum,
genu,
and body and the posterior one—splenium.
The place of the fusion is the isthmus.
It reaches its final shape in midgestation (week 20) but is still small and grows,
initially by addition of fibers and later by myelination.
The target volume is reached at the age of 6–9 years.
[3]
Various pathologies can affect the corpus callosum and their characteristic appearances on MRI.
Pathologies of the corpus callosum result in typical symptoms of interhemispheric discoordination.
