PURPOSE
To present a case of sudden isolated unilateral trochlear nerve palsy of new onset associated with a COVID-19 infection without a severe course.
METHODS
A 49-year-old previously healthy man suddenly noticed seeing double while going down the stairs to go out for the first time the day after the completion of medical treatment and home isolation for COVID-19. There was no systemic disease or history of trauma.
RESULTS
Magnetic resonance imaging of the brain and orbits was normal and the neurology examination revealed no pathology. The acute onset of the diplopia, the small vertical fusion amplitude, and the lack of facial asymmetry supported acquired trochlear nerve palsy.
CONCLUSIONS
Trochlear nerve palsy has rarely been reported in association with the various types of viral infections. To the best of our knowledge, this is the first case of isolated unilateral trochlear nerve palsy with no additional neurological finding or any radiological finding that is possibly associated with mild SARS-CoV-2 infection.
目的
报告一例新发性突发孤立性单侧滑车神经麻痹病例，该病例与新冠病毒感染相关且病程不严重。
方法
一名49岁既往健康男性，在完成新冠病毒感染的药物治疗和居家隔离后的第二天，首次出门下楼时突然发现复视。无全身性疾病或外伤史。
结果
脑部和眼眶的磁共振成像正常，神经学检查未发现病变。复视急性发作、垂直融合幅度小以及面部不对称不明显支持后天性滑车神经麻痹。
结论
滑车神经麻痹很少与各种类型的病毒感染相关报道。据我们所知，这是首例孤立性单侧滑车神经麻痹病例，无其他神经学发现或任何影像学发现，可能与轻度新型冠状病毒感染相关。
