Brain and upper extremity PET/CT findings of hyperglycemia-induced hemiballism-hemichorea.
Hyperglycemia-induced hemiballism-hemichorea is an uncommon movement disorder probably related to vascular insult of the basal ganglia in patients with poorly controlled diabetes. This rare clinical entity has been reported with abnormal brain findings on CT, MR, and F-18 FDG PET. The author presents additional PET/CT features of such an unusual dyskinetic syndrome with increased radiotracer uptake in the left motor cortex and musculature of the right shoulder girdle and upper extremity from hemiballism-hemichorea.
