The T2/FLAIR hyperintense lesion at the trigone of the left lateral ventricle has increased in size, now measuring 2.7 x 2.2cm. This is again seen to be contiguous with FLAIR hyperintensity more laterally within the left posterior temporal lobe that involves and expands the cortex. The white matter component demonstrates contrast enhancement and there is also irregular left posterior temporal lobe nodular sulcal enhancement.
Conclusion: Increase in size of the left temporal lobe lesion, which is favoured to represent a high grade glial series tumour.
