Fig. 2 Typical brain abscess on magnetic resonance imaging. (a) Axial T1-weighted image: abscess with a thin hyperintense capsule (white arrow), hypointense central necrosis, and a mass effect in the adjacent structures; (b) axial T2-weighted image: the same abscess with a thin hypointense capsule (white arrow), hyperintense central necrosis, and a peripheral hyperintense oedema; (c) axial diffusion-weighted image: the centre of the abscess is hyperintense; (d) axial image, cartography of apparent diffusion coefficient (ADC): the central component appears hypointense on ADC map; (e) axial T1-weighted image after gadolinium injection: the peripheral capsule (right arrow) is enhanced.
