PURPOSE
To alert ophthalmologists to the possibility of brainstem ischaemia in patients with isolated Horner's syndrome.
DESIGN
Observational case report.
METHODS
Neuro-ophthalmological and neuroimaging assessment of a 59-year-old woman presenting with an isolated Horner's syndrome after an episode of headache.
RESULTS
Horner's syndrome was pharmacologically localised to a first- or second-order sympathetic neuron on the right. Magnetic resonance imaging (MRI) showed a small ischaemic lesion at the transition between pons and midbrain, lateral to the anterolateral system involving the sympathetic tract on the right side.
CONCLUSION
An isolated Horner's syndrome may be the presenting sign of a brainstem infarction. This case report stresses the importance of a rational approach to Horner's syndrome and the need to order accurate MRI.
目的
提醒眼科医生注意孤立性霍纳综合征患者存在脑干缺血的可能性。
设计
观察性病例报告。
方法
对一名59岁女性进行神经眼科和神经影像学评估，该患者在一次头痛发作后出现孤立性霍纳综合征。
结果
通过药理学方法确定霍纳综合征定位于右侧第一或第二级交感神经元。磁共振成像（MRI）显示脑桥和中脑交界处有一个小的缺血性病变，位于前外侧系统外侧，累及右侧交感神经束。
结论
孤立性霍纳综合征可能是脑干梗死的首发症状。本病例报告强调了对霍纳综合征采取合理方法的重要性以及进行准确MRI检查的必要性。
