An unusual case concerning a patient with akinetic mutism (AM) due to spontaneous bilateral anterior cerebral artery occlusion is reported. Brain CT scan revealed the presence of mild low density foci presenting an irregular enhancement, which followed the distribution of mesial frontal gyri and paracentral lobulus, bilaterally. Right and left carotid angiographies showed bilateral occlusion of the anterior cerebral artery. Our case is characterized by an exclusive localization of the infarction in the frontal cortex. This finding suggests that a limited damage involving the anterior cerebral arteries territory could be, on its own, responsible for the AM syndrome.
报告了一例因自发性双侧大脑前动脉闭塞导致运动不能性缄默症（AM）的罕见病例。脑部CT扫描显示存在轻度低密度灶，呈现不规则强化，双侧沿额内侧回和中央旁小叶分布。左右颈动脉血管造影显示双侧大脑前动脉闭塞。我们的病例特点是梗死仅局限于额叶皮质。这一发现表明，大脑前动脉区域的有限损伤本身可能是导致AM综合征的原因。
