Cerebral abscess

Well defined thick-walled ring-enhancing lesion in the right frontal lobe with diffusion restriction, surrounding vasogenic edema and characteristic dual rim sign on SWI sequence. MRS revealed mildly reduced NAA with high lactate peak.
Case Discussion
Two major differentials for the present case are brain abscess and glioma. Dual rim sign helps in distinguishing cerebral abscess from glioma.
