Patient's first MRI on admission. Multiple hypointense, nodular lesions ranging in size from 5 to 9 mm were observed on T1W (A), T2W (B), and FLAIR C images, showing infratentorial and supratentorial distribution with partial preservation of the central parts. The lesions did not show diffusion restriction (not shown) and there was surrounding vasogenic edema, which was observed as a patchy signal increase on T2 and FLAIR images (B, C). There was no signal loss in the suscebtibility-weighted images (not shown). In contrast-enhanced images, ring-like enhancement was observed mostly, and homogeneous nodular enhancement was observed in a few smaller lesions (D). Note the high number and watershed localization of the lesions on post-contrast T1W axial MIP images (E). FLAIR fluid-attenuated inversion recovery, MIP maximum intensity projection, T1W T1 weighted, T2W T2 weighted

On MRI, multiple ring-enhancing lesions were observed (Fig. 1).
Control MRI after 2 months of anti-tuberculosis theraphy demonstrates resolution of the lesions. Precontrast T1W axial (A), T2W axial (B), FLAIR axial (C), post-contrast T1W axial (D), post-contrast T1W axial MIP images (E).

Two months after the onset of anti-tuberculosis therapy, follow-up cranial MRI showed near-complete resolution of the tuberculomas in the brain (Fig. 2).
