Abstract
Hemichorea is a rare manifestation of nonketotic hyperglycemia that usually affects Asian, elderly women with poor glycemic controland Non-contrast computerized tomography and T1- weighted Magnetic resonance imagingshows characteristic hyperintense basal ganglia lesions. Here we present a Sri Lankan female with poorly controlled diabetes presenting with hyperglycemic nonketotic chorea with CT and MRI- T1 showing hyperintense caudate and lentiform nucleus. Chorea completely disappeared 2 days after glycemic control and NCCT was repeated 4 days and 10 days after the glycemic control which showed rapid resolution of CT changesThe patient had poorly controlled diabetes, without any complications, suggesting that chorea might not be related to microvascular or macrovascular complications of diabetes.
