Arteriovenous malformations have only rarely been implicated as a cause of basal ganglia dysfunction. In four instances where such a lesion was uncovered, abnormal involuntary movements were present. In two, tremor involving the contralateral limbs occurred, while in others the head and neck were involved in dystonic movements and posture. The clinical and angiographic characteristics of these four patients have been assessed and are presented in detail in this report. The possible mechanism by which arteriovenous malformations may disturb the internal circuitry of the basal ganglia and induce symptoms are discussed.
动静脉畸形很少被认为是基底神经节功能障碍的原因。在发现有这种病变的4例病例中，均出现了异常的不自主运动。其中2例出现对侧肢体震颤，而在其他病例中，头颈部出现肌张力障碍性运动和姿势。对这4例患者的临床和血管造影特征进行了评估，并在本报告中详细介绍。本文还讨论了动静脉畸形可能干扰基底神经节内部神经回路并诱发症状的可能机制。
