A 64-year-old woman developed multiple brain abscesses of the basal ga
nglia associated with Klebsiella pneumoniae septicemia. Magnetic reson
ance (MR) images showed three different stages of the brain abscesses.
The images of early cerebritis of this site mimicked lacunar infarcti
ons or dilated Virchow-Robin spaces, The differentiation of the brain
abscess from lacunae and dilated Virchow-Robin spaces is discussed, to
gether with the evolution of the brain abscesses on MR images.
