Axial T2W and FLAIR images show irregular hyperintensities in the right basal
ganglia, frontal, and temporal lobes. Some signal abnormalities can also be seen
near the left basal ganglia. Minimal mass effect is noted on the anterior third ventricle.
Left: FLAIR image shows bilateral frontal lobe hyperintensities, right greater
than left, and in the corpus callosum.
Top right: coronal T1WI shows enlargement of the optic chiasm and slight
effacement of the third ventricle on the right.
Bottom right: coronal T1WI with gadolinium demonstrates enhancement of the
optic chiasm and multiple nodular lesions. The enhancing nodules are mostly
along VR spaces, as well as withing cortical sulci and on the brain surface.
Linear enhancement along the right lateral ventricle is the thalamostriate vein.
T1WI's with gadolinium show multiple enhancing nodules within the
basal cisterns in the subfrontal and suprasellar regions
Left and right: axial T1WI's with gadolinium show that this disease process
involves both hemispheres, both on the cortical surface and deep within the
Middle: posterior fossa axial T1WI with gadolinium reveals enhancement
of the medulla and leptomeningeal involvement along the undersurface of
the cerebellar hemispheres.
