Computed tomography (CT) was abnormal in 75% of 33 patients with pure motor hemiparesis (PMH). In 13 cases, lesions were detected in the capsular region; 10 were consistent with infarction, and 3 were of increased density consistent with hemorrhage. Seven had other vascular disorders, and four had nonvascular conditions. Of 20 patients with PMH with normal electroencephalogram (EEG), isotope scan, and cerebrospinal fluid, 11 had CT evidence of a lesion in the internal capsule-corona radiata region. In patients with PMH with normal CT, recovery was more complete and rapid than in those with CT evidence of a vascular lesion. In 5 cases, CT showed a capsular lesion, although the patients had never had any neurologic deficit.
33例纯运动性偏瘫（PMH）患者中，75%的患者计算机断层扫描（CT）结果异常。13例患者在囊区检测到病变；10例符合梗死表现，3例密度增加符合出血表现。7例有其他血管疾病，4例有非血管性疾病。20例脑电图（EEG）、同位素扫描和脑脊液均正常的PMH患者中，11例CT显示内囊 - 放射冠区有病变。CT正常的PMH患者恢复比有血管病变CT证据的患者更完全、更迅速。5例患者CT显示有囊区病变，尽管这些患者从未有过任何神经功能缺损。
