Brain imaging studies. (a) Pre-treatment brain magnetic resonance imaging scan showing bilateral mesial temporal high T2 signal intensity (arrows). (b) Pre-treatment brain positron emission tomography/computed tomography brain scan revealing a focus of intensely increased 18F-fluorodeoxyglucose uptake limited to the head of the right hippocampus (arrow) on a background of globally decreased 18F-fluorodeoxyglucose uptake. (c) Post-treatment brain magnetic resonance imaging scan showing marked improvement in the previously identified bilateral hyperintensities, which were replaced by atrophy (arrows). (d) Post-treatment positron emission tomography brain scan showing normal 18F-fluorodeoxyglucose uptake in the right hippocampus.
