case_images: Sagittal (A) and axial (B) T2W-weighted MRI of the cervical spine revealing marked hyperintense posterior columns.. Notes: The dashed line corresponds to the sectional plane of the axial view. The arrows point to the hyperintense signal of the posterior columns.. Abbreviations: T2W, T2-weighted; MRI, magnetic resonance imaging.

case_images: However, a spinal MRI showed marked T2W-hyperintense signal alterations confined to the posterior columns of the whole cervical spinal cord without pathological contrast enhancement (Figure 1), also determined as "inverted V" or "rabbit ears" sign.
case_images: Sagittal (A) and axial (B) T2W-weighted MRI at 6-month follow-up revealing subtotal remission of the posterior columns' signal alterations.. Notes: The dashed line corresponds to the sectional plane of the axial view. The arrows point to the former hyperintense signal of the posterior columns.. Abbreviations: T2W, T2-weighted; MRI, magnetic resonance imaging.

case_images: In accordance with the clinical improvement, the tibial nerve somatosensory evoked potentials were back to normal, and an MRI scan revealed subtotal remission of the posterior columns' signal alterations (Figure 2).
