Figure 3 (a-e): Multiple tuberculomas with perilesional edema exhibiting better defi nition of the wall on T1W magnetization transfer (MT) imaging in a 20-year-old man. T2W (a) and fl uid-attenuated inversion recovery (b) images show areas of central hypointensity surrounded by edema. T1W MT image (c) shows conspicuous hyperintense walls in all lesions. DWI image (d) shows restriction in the core of some of the lesions (arrows). (e) Postcontrast T1W MT image shows ring as well as disc enhancement of all lesions.
