目的从影像学角度观察非酮症性高血糖合并舞蹈症的CT及MRI影像学表现,加强对本病的认识并避免误诊。方法回顾性分析8例非酮症性高血糖合并偏舞蹈症患者CT及MRI表现。结果本文8例患者中6例表现为单侧肢体不自主运动,1例表现为精神异常,1例未出现肢体症状但出现头部MRI一侧尾状核T1WI高信号;MRI表现1例累及单侧壳核,1例累及单侧尾状核,1例累及双侧基底节区,5例累及单侧壳核及尾状核。颅脑CT表现中1例表现为双侧基底节区斑片状高密度影,7例表现为单侧基底节片状高密度,周围无明显低密度水肿带及占位效应。结论非酮症性高血糖合并偏侧舞蹈症脑部特征可以出现且病变特征性比较明显。
Objective To observe the CT and MRI features of non-ketotic hyperglycemia with chorea from the imaging point of view to enhance the understanding of the disease and avoid misdiagnosis. Methods The CT and MRI findings of 8 patients with non-ketotic hypercholesterolemia and chorea chorea were retrospectively analyzed. Results In the 8 cases, unilateral involuntary movement occurred in 6 of 8 patients. One patient showed abnormal psychosis. One patient showed no limb symptom but showed high signal of T1WI on the MRI side of the head. Side shell nucleus, one case involved unilateral caudate nucleus, one case involved bilateral basal ganglia, and five cases involved unilateral putamen and caudate nucleus. One case of brain CT manifestations of bilateral basal ganglia patchy high density, 7 cases showed unilateral basal ganglia flake high density around the area without significant low density edema and mass effect. Conclusion The non-ketotic hyperglycemia with hemophilia may appear brain features and lesions more obvious characteristics.
