We describe 12 cases of acute stroke in which clinical features of proximal posterior cerebral artery occlusion simulated the clinical syndrome of middle cerebral artery occlusion. The majority of patients developed contralateral hemiparesis, homonymous hemianopia, hemispatial neglect, and sensory loss or sensory inattention. All 8 patients with dominant hemisphere lesions were aphasic. Accurate diagnosis in each case was achieved only after a head CT, showing occipital lobe, thalamic, and inferomesial temporal lobe infarction. "Cortical" signs are probably explained by thalamic involvement. Recognition of this syndrome has implications for management and prognosis.
我们描述了12例急性卒中病例，其中大脑后动脉近端闭塞的临床特征类似于大脑中动脉闭塞的临床综合征。大多数患者出现对侧偏瘫、同向性偏盲、偏侧空间忽视以及感觉丧失或感觉忽视。所有8例优势半球病变患者均有失语。仅在头颅CT显示枕叶、丘脑和颞叶内侧下部梗死之后，才对每例患者做出准确诊断。“皮质”体征可能是由丘脑受累所致。认识这一综合征对治疗和预后具有重要意义。
