Male, 66 years old, with history of grade 2 astrocytoma status post RT + TMZ. Off of all treatment since a few years. Patchy, non-masslike T2/FLAIR hyperintensity is again seen within the pons and medulla showing no significant interval change in morphology or geographic extent. No associated enhancement is seen.A focus of susceptibility within the right posterior medulla, and a very small additional focus along the left posterior medulla, are unchanged, possibly representing foci of microhemorrhage or small cavernous malformations.Subcortical T2 hyperintensity within the right cuneus and in the right inferior frontal gyrus is unchanged. Likewise, scattered small foci of periventricular and subcortical white matter T2 hyperintensity are unchanged and nonspecific. No evidence of mass effect is seen. The ventricular system is stable in size and morphology. Prominence of the CSF space along the right cerebellar hemisphere is unchanged.
Compared to multiple recent examinations since 2/12/2015, there is no evidence of tumor recurrence or progression. Of note, signal abnormality in the brainstem is markedly improved since remote MRI from 8/2/2011.
