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.
偏身舞蹈症和全身性舞蹈症是与非酮症高血糖相关的罕见综合征。这种疾病通常折磨老年女性，可能预示着新发糖尿病的发作，通常为2型糖尿病。关于这个罕见病症的潜在病理生理学存在相互矛盾的报道。过去已经描述过磁共振成像的结果，且具有特征性。关于这种不寻常的运动障碍综合征的18F-氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（PET/CT）结果的报道非常少。本报告描述了这种罕见疾病的PET/CT特征。早期发现并迅速纠正高血糖可能会导致症状完全或显著改善。
