Ovoid well-defined heterogeneous but predominantly T1 hypointense / T2 hyperintense (which partially suppress on FLAIR) mass involving cortex and white matter of the posteroinferior left parietal lobe. A thin rim of flair hyperintensity surrounds its margin.
No concerning central or marginal enhancement. An equivocal segment of thin rim diffusion restriction at the anterolateral margin. No elevated CBV. No evidence of haemorrhage or calcification. Spectroscopy traces within show elevated choline and depressed NAA, consistent with tumour. Mild local positive mass-effect. Overlying calvarium is unremarkable.
No other intra or extra-axial mass.
Conclusion: Solitary left parietal lobe mass, most likely a low-grade glioma.
