Isolated oculomotor nerve palsy (ONP) attributable to mild closed head trauma is a distinct rarity. Its diagnosis places high demands on the radiologist and the clinician. The authors describe this condition in a 36-year-old woman who slipped while walking and struck her face. Initial computed tomography did not reveal any causative cerebral and vascular lesions or orbital and cranial fractures. Enhancement and swelling of the cisternal segment of the oculomotor nerve was seen during the subacute phase on thin-sectioned contrast-enhanced magnetic resonance images. The current case received corticosteroid therapy, and then recovered fully in 13 months after injury. Possible mechanism of ONP from minor head injury is proposed and previous reports in the literature are reviewed.
由轻度闭合性头部外伤引起的孤立性动眼神经麻痹（ONP）极为罕见。其诊断对放射科医生和临床医生都有很高要求。作者描述了一名36岁女性的这种情况，该女性走路时滑倒并撞到脸部。最初的计算机断层扫描未发现任何导致病因的脑和血管病变或眼眶和颅骨骨折。在亚急性期，薄层对比增强磁共振图像上可见动眼神经脑池段强化和肿胀。该病例接受了皮质类固醇治疗，伤后13个月完全康复。文中提出了轻微头部损伤导致ONP的可能机制，并回顾了既往文献报道。
