66-year-old female with right sided weakness showing left parietal cortical and sub cortical lesion A, B, C axial T2, FLAIR, T1 GAD. The lesion showed T2 and FLAIR hyper 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 rCBV of 1.05 F ADC image shows no diffusion restriction (ADC value measures around 1.2 × 10−3 × mm2/s. Collectively the findings are in favor of low-grade glioma. Histopathological examination confirmed the diagnosis diffuse astrocytoma WHO grade II
