Magnetic resonance images of the brain abscess. TIW = T1-weighted; T2W = T2-weighted; DWI = diffusion weighed imaging. A patchy abnormal signal was observed in the right parietal–temporal lobe, with a low signal on T1-weighted imaging surrounded by annular high signals, and a high signal on T2-weighted imaging surrounded by annular low signals around the lesion. Diffusion-weighted imaging showed high signals with patchy long T1 and long T2 signals around the lesion; the lesion appeared to be connected to the right lateral ventricle
