A 46 year-old woman presented with a weakness of the left side. MRI of the brain showed a left temporal meningioma, a left temporal lobe herniation and two high-signals in the right cerebral peduncle. The involvement of the pyramidal tract in the foot of the cerebral peduncle, in this case, results from temporal lobe hemiation. These findings are different from the mechanisms reported in other cases of ipsilateral hemiplegia. The ipsilateral hemiplegia syndrome was classically described by Ectors in relation to a meningioma of the foot of the third frontal circonvolution. Pathophysiological theories of ipsilateral hemiplegia are reviewed.
一名46岁女性出现左侧肢体无力。脑部磁共振成像（MRI）显示左侧颞部脑膜瘤、左侧颞叶疝以及右侧大脑脚两处高信号。在此病例中，大脑脚底部锥体束受累是由颞叶疝引起的。这些发现与其他同侧偏瘫病例报道的机制不同。同侧偏瘫综合征经典地由埃克特斯描述为与额下回底部的脑膜瘤有关。本文对同侧偏瘫的病理生理理论进行了综述。
