18F-fluorodeoxyglucose positron emission tomography/computed tomography in a case of non-ketotic hyperglycemia.
Hemichorea and generalized chorea are rare syndromes associated with nonketotic hyperglycemia. This disorder usually afflicts elderly females, and may herald the onset of new onset diabetes, usually type 2. There are conflicting reports of the underlying pathophysiology of this rare entity. Magnetic resonance imaging findings have been described in the past, and are characteristic. There are very few reports of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) findings of this unusual dyskinetic syndrome. This report describes the PET/CT features of this rare disease. Early detection and prompt correction of hyperglycemia may lead to complete or significant amelioration of symptoms.
