Within the right frontal lobe there is a region of high signal that predominantly involves the white matter tracts but invades the grey-white matter junction extending into the cortex of the right superior frontal gyrus. This area measures 49 x 40mm and demonstrates high signal on FLAIR and T2. Small foci of T1 post contrast enhancement identified. On DWI and ADC there is patchy diffusion restriction. A central well defined lobular area that is low signal on T1 and high signal on T2 is consistent with a region of cyst formation.
Elevated choline, reduced NAA consistent with glial series tumour, with minimal elevation of lactate suggested on one voxel.
NO elevation of CBV
There is minimal midline shift. No hydrocephalus. The basal ganglia and posterior fossa are normal.
Conclusion: Findings are most likely a right frontal glial series tumour, intermediate grade.
