Clinical question: Evaluate for growth of grade 3 oligodendroglioma with 1P19q deletion. Off all treatments since 2012. Signs and symptoms: As above. Pre-and post enhanced brain MRI:There is a focus of cortical and subcortical hemorrhagic encephalomalacia in the right posterior superior temporal gyrus without appreciable change in size or signal intensity since prior exam. Additional underlying white matter flair hyperintensity at this site also remains nearly identical to prior exam. There is mild ex vacuo dilatation of the trigone of right lateral ventricle similar to prior exam. There is no evidence of associated mass effect with this finding which is a similar observation is prior study. The involved cortex at this site demonstrated thin linear T1 hyperintensity consistent with mineralization similar to prior exam. Post enhanced images demonstrate no convincing evidence of abnormal enhancement. This is a similar observation is prior study. Findings consistent with stable treated tumor without change since prior exam.Unremarkable pre-and post enhanced brain MRI otherwise.
1.Stable post operative/treatment of a right posterior temporal mass without initial interval change as detailed.2.Unremarkable pre-and post enhanced brain MRI otherwise and stable since prior study.
