Magnetic resonance imaging of the brain and spinal cord at first attack, showing lesions indicative of multiple sclerosis. (a) Axial FLAIR image showing hyperintense lesions in the white matter of both hemispheres. (b) Coronal T1-weighted image showing a gadolinium-enhancing lesion near the left lateral ventricle. (c) Sagittal T2-weighted image showing lesions in the corpus callosum. (d) Sagittal T2-weighted image showing a hyperintense lesion on cervical spinal cord at C2 level.

Brain MRI fulfilled the Barkhof's criteria for MS diagnosis with several periventricular, subcortical, and callosal hyperintense lesions on T2-weighted and FLAIR images (Figures 1(a) and 1(c)), one of which (in the periventricular white matter of the left hemisphere) showed gadolinium-enhancement on T1-weighted sequences (Figure 1(b)). Additionally, cervical spinal cord MRI revealed a lesion at C2 level (Figure 1(d)).
Thoracic spinal cord MRI at second attack. (a) Sagittal T2-weighted image showing a hyperintense lesion at T3 level. (b) Sagittal T1-weighted image showing gadolinium-enhancement of the lesion at T3 level. (c) Axial T2-weighted image showing a hyperintense lesion at T11 level.

However, spinal cord MRI revealed one gadolinium-enhancing lesion in the thoracic segment at T3 level along with a nonenhancing lesion at T11 level (Figure 2).
