Type IVB lesions in a patient with MS. (A) Axial T2-FLAIR brain MRI shows multiple demyelinating lesions in the bilateral periventricular white matter. (B) All of the lesions show no enhancement on the CE T1WI. (C–E) Two of the lesions (arrows) in the posterior periventricular white matter are hypointense on the DWI, hyperintense on the ADC map, and hypointense on the eADC map, indicating chronic lesions with increased water diffusion due to severe tissue destruction.
