Bilateral paramedian thalamic infarcts are characterized by disturbance of consciousness, followed by persisting dementia, decreased spontaneity, apathy, amnesia and paralysis of eye movement. We report a 15-year-old boy with this syndrome, who exhibited transient coma at the onset. In addition to the typical symptoms, he complained of sensory disturbance in the lower extremities and face and the loss of taste sense. MRI showed symmetric paramedian thalamic infarction. There was no lesion in the midbrain. The etiology of infarct in this boy remained unknown despite extensive laboratory and neuroradiological examination. His sensory disturbance in the extremities and face may be due to extensive involvement of the inferolateral area of the thalamus by infarction of the paramedian thalamic artery. This patient illustrates that bilateral paramedian thalamic infarction can occur in a previously healthy child.
双侧丘脑旁正中梗死的特征为意识障碍，随后出现持续性痴呆、自发性活动减少、淡漠、失忆及眼球运动麻痹。我们报告一名患有此综合征的15岁男孩，其起病时表现为短暂昏迷。除典型症状外，他还主诉下肢和面部感觉障碍以及味觉丧失。MRI显示双侧丘脑旁正中梗死。中脑无病变。尽管进行了广泛的实验室和神经放射学检查，该男孩梗死的病因仍不明。他的肢体和面部感觉障碍可能是由于丘脑旁正中动脉梗死致使丘脑下外侧区域广泛受累所致。该患者表明双侧丘脑旁正中梗死可发生于既往健康的儿童。
