MR images of the cervicodorsal spinal cord. Sagittal T2WI (a) and STIR-T2WI (b) show a well-defined, ovoid-shaped, high-intensity lesion (black arrow) within the cervical cord at C2-C4, with mild fusiform expansion of the cord. On sagittal T1WI (c), the lesion is slightly hypointense (black arrow). After gadolinium administration (d), the lesion enhances intensely and homogeneously (white arrow).

MRI of the spinal cord revealed bifocal high-intensity white matter lesions on T2-weighted images (T2WI), one extending from the second to the fourth cervical (C2-C4) level and another at the conus medullaris (T12-L1), which enhanced after contrast administration (Figures 1 and 2).
MR images of the dorsolumbar spinal cord. Sagittal T2WI (a) and STIR-T2WI (b) show patchy hyperintense lesions involving the distal lumbar spinal cord and the conus medullaris (black arrows). Mild spinal cord edema is also present (white arrows). Incidentally, posterior disc bulging is visualized at the level of L5-S1 (black arrowhead). The lesions are isointense on T1WI (c). T1WI after intravenous gadolinium injection (d) demonstrates heterogeneous enhancement (white arrowhead).

MRI of the spinal cord revealed bifocal high-intensity white matter lesions on T2-weighted images (T2WI), one extending from the second to the fourth cervical (C2-C4) level and another at the conus medullaris (T12-L1), which enhanced after contrast administration (Figures 1 and 2).
Whole cord MR images 6 weeks after the first MRI. Sagittal T2WI (a) and STIR-T2WI (b) show resolution of the cervical lesion (white asterisks), whereas a slight hyperintensity is seen in the lumbar cord (black arrows). There are no abnormalities on sagittal T1WI without (c) and with intravenous gadolinium (d).
