Corpus callosum
The corpus callosum (plural: corpora callosa) is the largest of the commissural fibers, linking the cerebral cortex of the left and right cerebral hemispheres. It is the largest white matter tract in the brain.
Summary
located inferior to the cerebral cortices, and superior to the thalamus

Lesions of the corpus callosum
Lesions of the corpus callosum are uncommon and arise from multiple different etiologies. The lesions can be classified according to underlying pathophysiology 4-6.
Neoplasm
Typically, amongst neoplasms, only aggressive lesions can invade the corpus callosum as it is composed of very dense whi...
Article
Dysgenesis of the corpus callosum
Dysgenesis of the corpus callosum may be complete (agenesis) or partial (dysgenesis) and represents an in utero developmental anomaly. It can be divided into:
primary agenesis: corpus callosum never forms
secondary dysgenesis: corpus callosum forms normally and is subsequently destroyed
Epide...

Corpus callosum parts (mnemonic)
A useful mnemonic to help remember the parts of the corpus callosum, from anterior to posterior, is:
Remember Genu Before Splenium
Remember G Before S (as G comes before S alphabetically)
Mnemonic
R: rostrum
G: genu
B: body (trunk)
S: splenium

Marbled pattern of the corpus callosum
Marbled pattern of the corpus callosum has been described in the acute phase of neuromyelitis optica (NMO) and represents multiple overlapping lesions with heterogeneous signal 1. This is distinct from the more typical appearance of multiple sclerosis (MS) where smaller separate individual lesio...

Mnemonic
I: infections (e.g. tuberculosis, varicella, rotavirus, HSV)
M: Marchiafava-Bignami syndrome
A: AIDS encephalopathy
D: diffuse axonal injury and diffuse vascular injury

Cytotoxic lesions of the corpus callosum (CLOCCs)
Cytotoxic lesions of the corpus callosum (CLOCCs) represent a collection of disparate conditions that can cause signal change in the corpus callosum, usually involving the splenium.
Terminology
The term cytotoxic lesions of the corpus callosum (CLOCCs) has been proposed recently 12 as a more ...

Post-hydrocephalus corpus callosum damage
Post-hydrocephalus corpus callosum damage is seen both in the setting of, and following treatment for, long-standing hydrocephalus. The exact pathophysiology remains to be fully elucidated but both compression and rapid decompression with resultant changes in morphology have been implicated.

Barkovich classification of agenesis of the corpus callosum with interhemispheric cyst
The Barkovich classification of agenesis of the corpus callosum with interhemispheric cyst divides interhemispheric cysts that are diagnosed in individuals with concurrent agenesis of the corpus callosum into two types based on the presence or absence of communication with the ventricular system...

Asymmetric ventriculomegaly, interhemispheric cyst and dysgenesis of the corpus callosum (AVID)
Asymmetric ventriculomegaly, interhemispheric cyst, and dysgenesis of the corpus callosum (AVID) is a triad of congenital cerebral anomalies.
Radiographic features
markedly asymmetric enlargement of the lateral ventricles may be the initial finding on routine fetal morphology ultrasound.
