24-year-old male with blurring of vision. A, B Axial T2 and T1 post contrast showed T2 hyper-intense expanding lesion epicentered on the right brachium pontis extending into the pons and the right cerebellar hemisphere with focus of ring enhancement after contrast associated and mild mass effect. C Right para sagittal FLAIR image showing hyper intense mass at the right cerebellar hemisphere and multiple other deep and periventricular white matter hyper intense foci. D Intermediate echo spectroscopy curve shows high Cho levels and relatively low Cr and NAA levels. E rCBV color perfusion map for the same lesion shows area of relative hypo-perfusion (rCBV 0.84). F ADC image show Foci of diffusion restrictions at the right brain stem (ADC value measures around (0.98 × 10−3 × mm2/s). Collectively the findings are in favor of tumefactive demyelinating lesion. Post therapy follow up confirmed the diagnosis
