Tuberculosis conundrum - current and future scenarios: A proposed comprehensive approach combining laboratory, imaging, and computing advances

Figure 10  Magnetic resonance imaging - tuberculoma. A: Axial T2-weighted imaging shows a variable T2 hypointense circumscribed mass lesion in the right anterior frontal region, with surrounding perilesional edema; B: T1 weighted imaging shows a peripheral T1 hyperintense rim; C: Apparent diffusion co-efficient map shows restriction of diffusion; D: Susceptibility weighted imaging demonstrates fine punctate intralesional foci of blooming; E Post contrast T1 weighted imaging showing slightly irregular peripheral rim enhancement; F: T1 magnetization transfer images; G: Amide proton transfer weighted images show elevated magnetization transfer asymmetry in the periphery of the lesion; H: T1 post contrast imaging after completion of anti-tuberculosis treatment reveals significant reduction in the size of the previously seen ring enhancing lesion. APT: Amide proton transfer. Images courtesy Dr. Saini J, Professor, Neuroimaging & IVR, NIMHANS, Bangalore.
