There is a region of high FLAIR signal centred on the right insula, extending into the right inferior and posterior frontal lobe and anterosuperior temporal lobe. No contrast enhancement. There is increased perfusion, particularly in the right frontal white matter, corresponding to patchy areas of diffusion restriction.
No evidence of blood products. Spectroscopy in an area of high FLAIR signal shows an increased creatine: choline ratio, and slightly reduced NAA. Mild mass effect on the right lateral ventricle with no midline shift. No futher lesion.
CONCLUSION:
Right frontal tumour has features of a glioma with increased perfusion either indicates an oligodendroglial component or an anaplastic (WHO III) diffuse astrocytoma.
