小舞蹈病(Sydenham chorea)是一种运动障碍 性疾病,主要与β—溶血性链球菌感染有关。认为其病因是一种对尾状核及丘脑下核神经元抗原的抗体介导免疫反应。然而,由于此病起病隐匿,早期神经病理和放射学发现罕见,确切的病理生化机制尚不清楚。本文报告1例此病早期临床、脑电图和放射学发现,有助于对本病基本病理过程的评价。 Sydenham chorea is a movement disorder that is primarily associated with beta-hemolytic streptococcal infection. The etiology is thought to be an antibody-mediated immune response to the neurons of the caudate and subthalamic nuclei. However, due to the insidious onset of the disease, the exact pathological and biochemical mechanisms found in early neuropathology and radiology are unknown. This article reports a case of early onset of this disease, EEG and radiology findings, contribute to the evaluation of the basic pathological process of the disease.
