Isolated cases of astasia or ptosis have each been reported in ischemic or hemorrhagic strokes involving the thalamus. We report a 70-year-old man with a medical history of hypertension who presented with left ptosis and gait disturbance despite intact motor strength in the legs and normal sensory function. MRI of the brain showed an evolving subacute infarction confined to the anteromedial-medial part of the left thalamus with no other areas of recent infarction identified. To our knowledge, combined ptosis and astasia in thalamic infarction has not been reported in the English literature. We identified 11 patients with thalamic ptosis and 21 with thalamic astasia in the literature. Patients who had ptosis, or gait abnormality which would not be related to thalamic stroke, were excluded; for example, evidence of infarction in the hypothalamus, midbrain, pons, cerebellum, or cingulate gyrus.
孤立的步态失稳或上睑下垂病例分别在涉及丘脑的缺血性或出血性脑卒中患者中被报道过。我们报告了一例 70 岁男性，有高血压病史，尽管腿部运动力量完整且感觉功能正常，但出现左侧上睑下垂和步态障碍。脑部 MRI 显示一个亚急性进展性梗死，局限于左侧丘脑的前内侧-内侧部分，没有发现其他近期梗死区域。据我们所知，在英文文献中，没有报道过丘脑梗死合并上睑下垂和步态失稳。我们在文献中确定了 11 例丘脑性上睑下垂和 21 例丘脑性步态失稳患者。排除了有上睑下垂或步态异常但与丘脑性卒中无关的患者，例如下丘脑、中脑、脑桥、小脑或扣带回脑回的梗死证据。
