(a) Axial Fluid Attenuation Inversion Recovery (FLAIR) imaging demonstrating symmetric increased signal involving the basal ganglia and thalami bilaterally, (b) Increased signal intensity is also noted in the hypothalamus, anterior midbrain and to varying degrees in both medial temporal lobes.

Increased signal was also noted involving both medial temporal lobes, left greater than right (Figure 1).
Axial T1-weighted post-contrast imaging (a and b) demonstrating avid enhancement corresponding to the regions of T2/FLAIR signal abnormality.

These regions showed avid enhancement (Figure 2).
Axial (a) and sagittal (b) contrast enhanced computed tomography imaging of the chest demonstrates a well-defined cystic and solid mass containing punctate calcifications in the anterior mediastinum, without mass effect on the adjacent vascular structures.

The ultrasound was negative, but the CT demonstrated an anterior mediastinal mass (Figure 3).

T1-weighted post-contrast imaging (a and b) following surgery demonstrates near-complete resolution of the previously noted enhancement.
