focal thalamic tumefactive demyelinating lesion

A focal T2 / FLAIR hyperintensity involving right thalamus demonstrating mixed signal intensity on T2 with partial rim enhancement causing mild thalamic expansion indenting 3rd ventricle –*may suggest focal thalamic tumefactive demyelinating lesion*

Other differentials would be subacute infarct versus ? neoplasm.

No evidence of blooming on GRE. The lesion is relatively hyperintense on DWI .

No evidence of midline shift .
