Internuclear ophthalmoplegia (INO) is caused by lesions in the median longitudinal fasciculus. It is generally the result of primary intraaxial disorders, most commonly multiple sclerosis in young adults and infarction in older adults. Rarely, extraaxial disorders cause INO by compressing the brainstem. We report two patients with INO resulting from subdural hematoma with transtentorial herniation. These cases demonstrate that INO is a reliable, but not a pathognomonic, sign of a primary intraaxial disorder.
核间性眼肌麻痹（INO）由内侧纵束病变引起。它通常是原发性轴内疾病的结果，最常见于年轻人的多发性硬化症和老年人的梗死。极少数情况下，轴外疾病通过压迫脑干导致INO。我们报告了两例因硬膜下血肿伴小脑幕切迹疝导致INO的患者。这些病例表明，INO是原发性轴内疾病的一个可靠但非特异性的体征。
