Lesions of the corpus callosum (differential)

Lesions of the corpus callosum are uncommon and arise from multiple different aetiologies. The lesions can be classified according to underlying pathophysiology 4-6.

Congenital
Demyelination
Infection
Leukodystrophy
Neoplasm

Typically, amongst neoplasms, only aggressive lesions can invade the corpus callosum as it is composed of very dense white matter tracts which act as a barrier to tumour spreading 1.
