40-year-old female with left hemiparesis showing right fronto-parietal cortical and sub cortical lesion A, B, C axial T2, T1, T1 post contrast. The lesion showed T2 hyper intense, T1 hypo intense signals with no enhancement after contrast administration, D intermediate echo spectroscopy curve shows relatively high Cho levels and low Cr and NAA levels. E rCBV color perfusion map for the same lesion shows area of relative hyper-perfusion rCBV 1.6. F ADC image shows relative diffusion restriction (ADC value measures around 0.9 × 10−3 × mm2/s). Collectively the findings are in favor of low-grade glioma. Histopathological examination confirmed the diagnosis diffuse astrocytoma WHO grade II
