FIG 1. Tuberculous meningitis with tuberculoma.
A, T2-weighted image through the mesencephalon shows a hyperintense lesion on the left side, along with a hyperintense region with central hypointense specks (arrow) in the right perimesencephalic cistern, merging with the lateral margin of the midbrain.
B, On T1-weighted image, the cisternal lesion appears isointense relative to white matter, with central hypointensity; the left midbrain lesion also appears isointense.
C, MT-SE T1-weighted image shows the left midbrain lesion and the right cisternal lesion as hyperintense, with central hypointensity extending to the remaining margins of the midbrain (arrow).
D, Postcontrast MT-SE T1-weighted image shows these meningeal and parenchymal lesions with marked enhancement.
