Figure 3b: (A and B) 31 year old male presented with three episodes of recurrent myelitis interspersed with one episode of optic neuritis over a period of 18 months. Initial MRI brain was normal. MRI of the cervical cord showed (Fig. 3A) on T2 W image, a linear contiguous lesion spanning more than 3 vertebral segments suggestive of longitudinally extensive transverse myelitis. On his fourth hospital admission, he presented with headache, disorientation and worsening of lower limb power. MRI brain (Fig. 3B) showed large lumpy posteriorly situated subcortical lesions.
