case_images: Axial T2 FLAIR showed cortical and subcortical hyperintensities within the
  brain parenchyma involving the left middle frontal gyrus, right superior
  frontal gyrus, right parietal cortex, left insula and right occipital lobe,
  and multiple subependymal nodules (A, B). Axial T1 post-contrast (C) showed
  enhancing subependymal nodule at the right foramen of Monro and smaller ring
  enhancing subependymal nodule along the posterior periventricular right
  white matter.

case_images: Monro with no hydrocephalus, along with few T2 white matter signal changes in the periventricular white matter (Figure 1).
case_images: Sagittal T2 of the cervical spine showed an abnormal T2 hyperintense signal
  associated with edema involving the medulla and the upper cervical cord,
  extending to C2-3 level (A). Improvement of these signal changes on
  follow-up scan 2 years later (B).

case_images: MRI scan of the cervical spine revealed an area of high T2 signal associated with edema involving the medulla and the upper cervical cord, extending to C2-3 level (Figure 2). MRI scan of the thoracic spine demonstrated a T2 hyperintense signal from T7 through T10, measuring approximately 5.5 cm in craniocaudal dimension with edema most pronounced at T8.
case_images: Sagittal T2 of the thoracic spine showed an abnormal T2 hyperintense signal
  from T7 through T10, measuring 5.5 cm in craniocaudal dimension. The
  edematous quality of this lesion is most pronounced at T8. There is a
  similar T2 hyperintense area within the right hemicord and dorsal cord at
  level T12.
