Focal T2 hyper intensity measuring about 4.5 x 4.0 cm, with surrounding vasogenic edema, seen in the sub cortical right posterior frontal lobe. A small focus of bleed is seen within it on SWI. No significant diffusion restriction is seen. Minimal enhancement is seen in the lesion on the post contrast study. MR spectroscopy shows increased lactate & lipid levels, reduced NAA peak and high choline peak. Impression: Focal lesion in the right posterior frontal lobe, with MRI & MRS features, suggestive of a neoplastic lesion.
