Pure motor hemiplegia (PMH) is commonly attributed to lacunar infarction of internal capsule or basis pontis. We report 7 patients of pure motor hemiplegia as a result of small or moderate size putaminal haemorrhage. All the patients had normal median somatosensory evoked potentials. Central Motor Conduction Time (CMCT) to upper limb was not recordable in all 3 patients with complete hemiplegia. Three of seven patients had complete and four had partial recovery. Anterioposterior extension of small or moderate size putaminal haemorrhage seems to spare the medially located sensory fibres in the internal capsule. On the basis of our results, lateral putaminal haemorrhage should be considered in the differential diagnosis of PMH.
纯运动性偏瘫（PMH）通常归因于内囊或脑桥基底部的腔隙性梗死。我们报告了7例因小或中等大小的壳核出血导致的纯运动性偏瘫患者。所有患者的正中体感诱发电位均正常。3例完全性偏瘫患者均无法记录到上肢的中枢运动传导时间（CMCT）。7例患者中有3例完全恢复，4例部分恢复。小或中等大小的壳核出血前后延伸似乎使内囊内侧的感觉纤维得以保留。根据我们的结果，在PMH的鉴别诊断中应考虑外侧壳核出血。
