FIG 4. Images acquired after surgical aspiration and antifungal therapy; cerebral abscess has resolved, leaving focal gliosis.

A, FLAIR (7000/105; TI, 2500) shows hyperintense signal in the left frontal lobe (arrow).

B, Postcontrast T1-weighted image (650/17) shows a band of contrast enhancement at the site of treated abscess (arrow).

C, DW image (b = 1000 s/mm²) shows symmetric signal intensities in frontal lobes.

D, ADC map shows minimal hyperintensity (arrow) in left frontal lobe, a finding consistent with gliosis. Mean ADC is 1.87 ± 0.08 (10^-3 m²/s).
