To assess the radiological MRI findings of diseases affecting the corpus callosum. 2.
To review and illustrate these diseases in order to establish the correct differential diagnosis.
The corpus callosum plays a fundamental role in the transfer of information and integration between the hemispheres.
Different pathologies affect the corpus callosum,
including in large groups: tumoural diseases,
endocrine and metabolic causes,
infectious agents and toxic insults,
Radiologist should know their imaging features in order to establish the correct differential diagnosis.

Imaging findings OR Procedure details
The corpus callosum is the principal supratentorial cerebral commissure (white matter tract) connecting symmetrical areas of cerebral hemispheres (between the parietal lobes,
posterior frontal and superior temporal regions).
It is divided in four segments: rostrum,
body and splenium.
It forms during embryogenesis,
between the 8th and 20th week of life.
It develops in an anterior-posterior direction except for the rostrum,
which is the last to form.
It contains very compacted myelinated...
This exhibit has revised and illustrated different pathologies affecting the corpus callosum based on radiological MRI findings,
in order to establish a correct differential diagnosis.
