Figure 9 (a–j): Right frontal tuberculoma in a 50-year-old male patient on antituberculous therapy with follow-up every 4 months for a total period of 1 year. The tuberculoma shows mixed intensity on the T2W images (a), slight hyperintensity on the T1W images (b), and hyperintensity on the magnetization transfer (MT) T1W images (c), with enhancement on the immediate contrast-enhanced T1W images (d) in all the studies. The hyperintense portion of the lesion is cellular with a very small necrotic fraction appearing hypointense on the MT T1W images. The cellular and total volumes of the lesion are seen to gradually decrease over 1 year on serial imaging. This is associated with a reduction in edema (T2W images) at each study time point. Color-coded fractional anisotropy (FA) map (e) shows gradual recovery of FA values with time in white matter regions. The perfusion indices [i.e., cerebral blood volume (f), cerebral blood fl ow (CBF) (g), ktrans (h), and ve (i) map] from the corresponding sections reveal a gradual decrease in their respective values at each time point over 1 year.
