Cerebral abscess

A small lesion with a thin, uniform rim of contrast enhancement and moderate associated vasogenic edema is noted in the left postcentral gyrus. Note that the periphery of the lesion is slightly hypointense on the coronal FLAIR scan, which is characteristic of an abscess, together with restricted diffusion (well seen in this patient, but with DWI not presented).
