Fig 2. Tubercular abscess in the right basal ganglia of a 25-year-old woman.

A well-defined hyperintense lesion is seen with a hypointense wall on axial T2-weighted image (A), which shows ring enhancement on postcontrast T1-weighted image (B). Diffusion-weighted image shows homogeneous hyperintensity in the cavity (C) with low ADC (0.54 x 10^–3 mm²/s) (D). PMRS from the center of the lesion with a voxel size of 2 mL shows predominant lipid peak (Lip, 1.3 ppm) (E). Culture from pus shows the presence of Mycobacterium tuberculosis.
