Oculomotor nerve palsy following traumatic brain injury is a rare entity. A head injury can result in diffuse neuronal axonal injury with subsequent microbleed within the nerve tissue. We report an unusual case of a patient who presented with complete isolated right third nerve palsy following a road traffic accident. In this patient, magnetic resonance imaging (MRI) revealed swelling and edema of the right oculomotor nerve along its cisternal segment with contrast enhancement. The acquisition of susceptibility-weighted images on MRI helped to clinch the diagnosis of intraneural hemorrhage as a cause of post-traumatic oculomotor nerve palsy.
颅脑损伤后动眼神经麻痹较为罕见。头部外伤可导致弥漫性神经元轴索损伤，随后神经组织内出现微出血。我们报告了一例不同寻常的病例，该患者因道路交通事故后出现完全性右侧动眼神经麻痹。该患者的磁共振成像（MRI）显示右侧动眼神经在其鞍旁段肿胀和水肿，伴有对比增强。MRI 上磁敏感加权成像的获取有助于确定动眼神经外伤性麻痹的病因是神经内出血。
