Computer tomography showing hypodense areas bilaterally in the temporal lobes indicating edema (arrows) (A). MRI of the brain with T1WI with gadolinium contrast (B), apparent diffusion coefficient (ADC) image (C), and diffusion-weighted imaging (DWI) (D). Multiple peripherally contrast-enhancing lesions with perilesional edema were found both supra- and infratentorial (B). A thin ependymal contrast enhancement is found. Diffusion imaging (C,D) show reduced signaling in the parenchymal lesions and in the content of the posterior horns, indicating multiple abscesses and ventriculitis.

CT brain showed no sign of abscess or empyema; bilateral diffuse low-density areas were observed in the frontal and temporal lobes, indicating edema (Figure 1A). On day 7, MRI with contrast enhancement revealed multiple brain abscesses (Figures 1B-D) and reduced diffusion, indicating ventriculitis.
