MRI study obtained 3 months after the prior study (28 weeks post op, ~4 months post end of Stupp protocol) demonstrates increasing volume of adjacent high FLAIR signal, extending further anteriorly into the frontal lobe and further superiorly to the frontoparietal white matter at the vertex. There is also mild increase in FLAIR hyperintensity into the right cerebral peduncle. There is increasing adjacent peripheral enhancement. The region of contrast enhancement shows significant elevation in choline, reduction in NAA and increase in lactate.
There is increasing susceptibility within the area of contrast enhancement in keeping with haemorrhage.
