FIG 3. Images acquired before abscess aspiration on hospital day 15.
A, FLAIR image (9000/105; TI; 2500) shows a poorly defined left frontal mass (arrow).
B and C, Postcontrast axial (B) and coronal (C) T1-weighted images show a thin, well-defined enhancing wall, consistent with cerebral abscess.
D, DW image (b = 1000 s/mm2) shows marked increased signal intensity is present in this mass (arrow).
E, Marked hypointensity (arrow) on ADC map is consistent with restricted diffusion. Mean ADC is 0.56 ± 0.05 (10-3mm2/s).
