A case of interhemispheric subdural hematoma ( ISH ) is presented and discussed. This disorder is a rare form of intracranial hemorrhage, which classically presents as an isolated paresis of one leg or a hemiparesis worse in the leg than the arm. The majority of cases are due to occipital trauma because of the anatomy of the bridging veins. Chronic interhemispheric hematomas are rare since the natural history of these lesions is to spread out over the cerebral convexity. Conservative treatment for ISH may be beneficial unless neurological deterioration necessitates early operative intervention.
本文报告并讨论了一例大脑半球间硬膜下血肿（ISH）病例。这种疾病是一种罕见的颅内出血形式，典型表现为单腿孤立性轻瘫或偏瘫，腿部症状比手臂更严重。由于桥静脉的解剖结构，大多数病例是由枕部外伤引起的。慢性大脑半球间血肿很少见，因为这些病变的自然病程是蔓延至脑凸面。除非神经功能恶化需要早期手术干预，否则ISH的保守治疗可能有益。
