White matter demyelination is seen involving the left peritrigonal region and extends through the forceps major fibers and splenium of corpus callosum to the contralateral side. It displays bright signal on T2 and FLAIR, low signal on T1 and enhances after contrast giving the appearance of open ring. The bright signal on DWI is believed to be T2 shine through effect as there is no evidence of restriction on ADC map. Another two plaques are seen at the left aspects of medulla oblongata and pons. Double inversion recovery sequence DIR delineates the lesions better due to suppression of signal from the white matter and CSF. Moreover, it detects involvement of the fornix as well.
