Transverse Myelitis

  • Etiology: infectious / postinfectious leading to cord inflammation, demyelination
  • Imaging: long segment (> 2 vertebral bodies) of centrally located T2 increased signal occupying greater than two-thirds of the cross-sectional area of the cord, variable pattern of enhancement, no restricted diffusion, smooth cord enlargement

Cases of Transverse Myelitis

MRI of transverse myelitis
Sagittal and axial T2 MRI of the thoracic spine shows centrally located continuous bright signal through the thoracic spinal cord that ends just above the conus medullaris.
