Case 13. 58-year-old patient with diabetes presented with altered mental status and multiple abscesses resulting from microaerophilic streptococcus. Gram-positive cocci were found on lumbar CSF analysis as well. Signal abnormality in the periventricular white matter and numerous abscesses (arrows) distributed throughout the deep and subcortical white matter are seen on proton density–weighted (2000/19/1 [TR/TEeff/excitation]) (A) and T2-weighted images (2800/256/1) (B). The irregular ventricular debris (arrowheads) is more clearly demonstrated on the proton density–weighted image (A). T1-weighted image (600/31/1) (C) obtained after intravenous administration of gadopentetate dimeglumine show minimal ependymal enhancement (arrows)
