  		Figure 1. A 22-year-old female with a medical history of acute lymphocytic leukaemia. (a) Post-contrast CT scan shows a ring-enhancing cystic lesion in the left frontal lobe. The lesion is hypointense on (b) the T1 weighted image and (c) hyperintense on the T2 weighted image with a focal peripheral oedema and a mild mass effect. A small pus-fluid level in the dependent portion of the lesion is shown. (d) Post-contrast T1 weighted image shows a ring-enhancing cystic lesion with several enhancing daughter nodules. With (e) the diffusion weighted image, the signal intensity of the lesion is hypointense with a corresponding marked hyperintensity on (f) the apparent diffusion coefficient (ADC) map. The small gravity-dependent portion is hyperintense on the diffusion weighted imaging (DWI) and shows hypointense signal intensity on the ADC map, indicating restricted diffusion.

  		Figure 2. A-60-year-old man with brain abscess in the left temporal lobe. (a) Post-contrast CT scan shows a ring-enhancing lesion in the left temporal lobe. The lesion is hypointense on (b) the T1 weighted image and (c) hyperintense on the T2 weighted image with extensive peripheral oedema and a mass effect. (d) Post-contrast T1 weighted image shows a ring-enhancing cystic lesion. The lesion shows a heterogeneous signal intensity on (e) the diffusion weighted image and inversely heterogeneous signal intensity on (f) the apparent diffusion coefficient (ADC) map. (g) Photomicrograph shows that the abscess tissues contain numerous viable inflammatory cells (white arrows), such as neutrophils, lymphocytes and histiocytes, and prominent necrotic cellular debris (black arrows) in the bloody background (Haematoxylin and Eosin, x200)
