PP63. PROGRESSIVE T2/FLAIR SIGNAL CHANGE AFTER LOW-GRADE GLIOMA RESECTION – WHAT DOES IT SIGNIFY?

BACKGROUND: Several international series’ have demonstrated the importance of extensive resection in controlling Low Grade Glioma (LGG). After surgery, regular MRI monitoring is undertaken for evidence of recurrence. Since LGG are typically demonstrated as hyperintense signal on T2 and FLAIR MRI scans, an increase in T2/FLAIR signal around the resection cavity would be expected to signify tumour progression. We describe our experience and...
