Magnetic resonance imaging (MRI) brain, cervical, and thoracic spine. (a) Sagittal fluid-attenuated inversion recovery brain MRI. More than 50 supra and infratentorial white matter lesions were observed with four new supratentorial and six new infratentorial lesions with no enhancing plaques to suggest acute demyelination. (b) Sagittal short-tau inversion-recovery (STIR) cervical MRI. Multiple demyelinating plaques were seen within the right anterior cord at the level of the dens and C2, the right posterolateral cord at C3 and C4, right lateral cord at C4 and C5, and the left posterior cord at levels C6-7. (c) Sagittal STIR thoracic MRI. Enhancing intradural extramedullary thoracic tumor occupies the left spinal canal at T7 with severe spinal cord stenosis and mass effect. (d) Sagittal T1 thoracic MRI with contrast. Dural tail extends superiorly.
