Improvement of a patient's essential tremor (ET) after a stroke has rarely been reported. In such patients, cerebral imaging could help to identify structures involved in the maintenance of ET and improves the knowledge of its physiopathology. This article reports the disappearance of ET, after a stroke in 4 patients and reviews similar previously published cases. These cases suggest that the interruption of cerebellar loops during a stroke could be responsible for the disappearance of ET.
脑卒中后患者的原发性震颤（essential tremor，ET）改善的情况鲜有报道。此类患者的脑部影像学检查有助于识别与 ET 维持相关的结构，并加深对其病理生理学的认识。本文报道了 4 例脑卒中后 ET 消失的病例，并对既往发表的相似病例进行了复习。这些病例提示脑卒中时小脑环路的中断可能导致 ET 的消失。
