Figure 1 (a-h): Tuberculous meningitis with vasculitis. T2W image (a) shows no apparent signal abnormality in the basal brain parenchyma. The corresponding magnetization transfer T1W image (b) shows hyperintensity in the perimesencephalic and supreseller cisterns. On DWI (c) restriction is noted in the left temporal region. The postcontrast T1W image (d) shows abnormal enhancement along the perimesencephalic and supraseller cisterns. In the same patient, axial sections at a higher level show hyperintensity on a T2W image (e) in the left middle cerebral artery (MCA) territory with hyperintensity on DWI (f) and low ADC values in the ADC map (g) suggesting a large left middle cerebral artery (MCA) territory infarct. The postcontrast T1W image (h) shows abnormal enhancement in the left caudate nucleus region
