MRI shows multiple white matter / corpus callosal / callososeptal hyperintense plaques (T2 and FLAIR) in this patient with multiple sclerosis. Some of these are iso-intense to CSF and hypointense on T1 & FLAIR, compatible with cystic changes (left cerebral hemisphere) in chronic MS lesions.
Necrosis and atrophy with cystic changes are common in chronic MS lesions, as shown here.
