Bilateral thalamic infarctions are usually caused by occlusion of the "Artery of Percheron" (AoP). Thalamopeduncular syndrome is among the most common presentations of AoP occlusion. A 59-year-old male presented abrupt decreased level of consciousness. After several weeks, on regaining consciousness, he exhibited oculomotor abnormalities, ataxic gait, cervical dystonia, and cognitive and behavioral changes. Magnetic resonance imaging disclosed thalamic, subthalamic, mammillary and midbrain infarction. Clinical features suggestive of bilateral thalamopeduncular syndrome were identified. Besides the presence of cognitive impairment and behavioral symptoms, cervical dystonia was evident, possibly resulting from interruption of the interconnections among basal ganglia, thalamus, subthalamus, midbrain and cerebellum.
双侧丘脑梗死通常由大脑后动脉丘脑穿通动脉（Percheron动脉，AoP）闭塞引起。丘脑脚综合征是AoP闭塞最常见的表现之一。一名59岁男性突然出现意识水平下降。数周后，意识恢复时，他出现了动眼神经异常、共济失调步态、颈部肌张力障碍以及认知和行为改变。磁共振成像显示丘脑、丘脑底核、乳头体和中脑梗死。发现了提示双侧丘脑脚综合征的临床特征。除了存在认知障碍和行为症状外，颈部肌张力障碍明显，可能是由于基底神经节、丘脑、丘脑底核、中脑和小脑之间的联系中断所致。
