case_images: Axial heavily fluid weighted T2 (A), postcontrast FLAIR (B), precontrast T1
  (C) and postcontrast T1 (D) weighted MR images at the pontomesencephalic
  junction reveal symmetric, smooth enhancement of the oculomotor nerves.
  Axial heavily fluid weighted T2 (E), postcontrast FLAIR (F), precontrast T1
  (G) and postcontrast T1 (H) weighted MR images at the lower pons reveal
  symmetric, smooth enhancement of the facial nerves involving the meatal and
  labyrinthine segments.

case_images: Magnetic resonance imaging (MRI) of the brain with and without contrast revealed abnormal smooth enhancement of the bilateral oculomotor, trigeminal, facial, and vagus nerves (Figure 1).
case_images: Axial precontrast (A) and postcontrast (B) T1-weighted MR images of the spine
  at the C5-6 level show symmetric, bilateral, smooth anterior and posterior
  nerve root enhancement. Axial precontrast (C) and postcontrast (D)
  T1-weighted MR images of the cauda equina reveal smooth nerve root
  enhancement without nodularity. Coronal T1 postcontrast reconstruction (E)
  of the cauda equina reveals diffuse nerve root enhancement in long axis.

case_images: MRI of the entire spine obtained with and without contrast showed similar smooth enhancement of spinal nerve roots at many levels, most conspicuous in the cauda equina and cervicothoracic junction (Figure 2).
