Figure 1: (a) Sagittal T2WI of the spine showing coalescing of multiple short segment lesions in a patient with relapsing-remitting multiple sclerosis at onset of disease and on follow-up once she entered the progressive phase of disease. (b) Sagittal T2WI of the spine showing a relapsing-remitting patient with multiple sclerosis with a short segment lesion superimposed on a longer patchy lesion at onset of disease. (c) Sagittal T2WI of the spine showing patchy ill-defined lesions more than 3 vertebral segments involving the entire cervicothoracic cord and axial T2WI of MRI brain with clinically definite multiple sclerosis in a patient with secondary progressive disease. (d) Sagittal T2WI (left) of the cervical spine showing a longitudinally extensive cord lesion with edema and corresponding T1WI (right) with T1 hypointensity within the cervical cord in a patient with neuromyelitis optica.
