Electroencephalogram in bipolar montage of our patient showing an occipital-predominant
generalized epileptiform discharge (recorded sensitivity 7 muV/mm, time base 30 mm/s,
low-frequency filter 1 Hz, high-frequency filter 70 Hz, notch filter off).

Magnetic resonance imaging of our patient's brain showing symmetric T1-hyperintense
signal (A) and corresponding decreased susceptibility signal (B) within the globi
pallidi bilaterally.

She had a brain magnetic resonance imaging during that hospitalization that showed T1-hyperintense signal and decreased susceptibility signal within the globi pallidi bilaterally in a symmetric pattern and a head CT that showed moderate progression of calcifications in the bilateral globi pallidi and the subcortical white matter of both frontal lobes when compared with the prior CT done at age 5 years (Figures 3 and 4).
Computed tomography of our patient's brain showing dense calcification in the bilateral
globi pallidi (arrows) and subtle calcification (arrowheads) in the bilateral frontal
white matter.
