(A) T2-weighted image with multiple patchy high-intensity signals and "target sign". (B) T1-weighted post-gadolinium contrast image with multiple nodular lesions and peripheral oedema. (C) T2-weighted image and T1-weighted post-gadolinium contrast image done three months later with approximate disappearance of the lesions.

Figures 1A,B show multiple lesions on her brain's magnetic resonance imaging (MRI). The improvement of brain MRI is shown in Figure 1C.

(A) T2-weighted image with multiple patchy hyper-intensity signals and "target sign". T1-weighted post-gadolinium contrast image with multiple nodular enhancing lesions, similar to military tuberculosis. (B) T2-weighted image and T1-weighted post-gadolinium contrast image done after regular ATT for a month with no significant improvement. (C) T2-weighted image and T1-weighted post-gadolinium contrast image done after intrathecal injections for one month with significant decreased lesions.

In terms of auxiliary examination, CT showed no lung abnormalities, while brain MRI revealed multiple lesions (Figure 2A). Brain MRI showed no significant changes compared with the previous scan (Figure 2B). Moreover, the size and number of lesions were significantly reduced on brain MRI (Figure 2C).
