Findings was changed:

MRI of the brain demonstrates, within the left occipital lobe, a rounded region demonstrating central high T2, low T1 signal is demonstrated. It is bounded by a region of relative low signal on T2 and surrounded by extensive vasogenic oedema. 

Diffusion weighted-weighted imaging demonstrates marked restriction, and the periphery of the lesion demonstrated bright ring ring enhancement with with somewhat shaggy borders. 

MRS (performed in of the lesion(TE = 144 ) has a noisy base linebaseline but an inverted lactate lactate peak is is none the less visible, as are reduced choline, creatine, and NAA peaks. 

Findings are consistent with a cerebral cerebral abscess.
