Figure 4: (A-D) Coronal T2W MRI image (A) shows an iso- to hypointense left parasagittal frontal lobe mass (black arrow), with altered marrow signal (white arrow) in the overlying parietal bone. Magnified coronal T2W MRI images (B,C) show a few hypointense dots (open arrows) within the hyperintense granulomas (white stars) separated by hypointense walls (white arrows), giving the "dot-in-circle" sign. Diffusion-weighted MRI image (D) shows small hyperintense areas (arrow) of restricted diffusion, probably representing microabscesses.
