Neuropsychological Impact of Bilateral Cerebral Abscesses in an Adolescent

Figure 1. T1-weighted contrast-enhanced coronal image from the day of admission shows abscesses with typical thick-walled enhancement in left ventral thalamus and right superior frontal gyrus, just above the cingulate gyrus.

Figure 2. T2-weighted axial image from day of admission shows left thalamic abscess creating mass effect on the fornix and edema extending into the posterior limb of the internal capsule, causing mass effect on the left optic tract (not shown).

Figure 3. T1-weighted contrast-enhanced coronal image at 8 weeks post-operative shows minimal residual inflammatory enhancement around the contracted abscess cavities. Edema is nearly resolved in the left thalamus and is significantly diminished around the right frontal abscess.
