Follow-up MRI of the brain without contrast on day 49 showed stable size and distribution of the signal changes, but there were encephalomalacic changes within the lesions of the frontal lobes (Fig. 4).
MRI cervical spine with and without contrast shows no evidence of cord compression and degenerative changes.
