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.

Monro with no hydrocephalus, along with few T2 white matter signal changes in the periventricular white matter (Figure 1).
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).

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.
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.
