Abstract
A 76-year-old woman with a history of diabetes mellitus presented with right-side dominant generalized chorea. At presentation, her blood glucose level was 500 mg/dL with an HbA1C of 11%. Because the patient had been on levodopa treatment from her primary physician, a dual-phase 18F-FP-CIT PET scan was performed. The early-phase images showed increased perfusion in the bilateral striatum, and the delayed-phase images revealed decreased uptake in the left caudate. Hyperperfusion in the striatum may indicate the acute phase of hyperglycemic chorea. This image illustrates the advantage of adding early-phase scans in 18F-FP-CIT PET in differentiating various hyperkinetic and hypokinetic disorders.
