FIG 3. Patient 2. A 31-year-old man with fever, seizures, and weakness of the left upper extremity. DW images were superior to conventional MR images showing re-accumulation of pus and well correlated with increased CRP levels and WBC counts.
A–C, Axial contrast-enhanced T1-weighted shows a peripheral enhancing lesion with a hypointense center in the right parietal region. Hyperintensity at DW imaging (B) and a low ADC (C) suggest abscess formation with restricted diffusion due to pus.
D–F, One day after surgery, images show decreased size of the abscess (D), hypointensity at DW imaging (E), and a high ADC of 2.56 x 10 –3mm 2/s (F).
