Fig 2.

A 48-year-old man (group 3) with cerebral fungal abscess.

A, Axial T2-weighted image shows a relatively isointense intra-axial lesion with surrounding hyperintense vasogenic edema in the right frontoparietal region.

B, Corresponding axial ADC map shows lower signal intensity of the lesion compared with the normal-appearing brain parenchyma, consistent with relatively decreased diffusion, as typically seen within brain abscesses. The lesion is surrounded by increased diffusion of vasogenic edema.

C, Postcontrast axial T1-weighted image corresponding to A and B demonstrates irregular, predominantly peripheral enhancement of the mass.
