Abstract

Objectives: To draw attention to acute positional vertigo and central positional nystagmus (CPN) developing as the sole features of cerebellar nodulus infarction.

Background: The cerebellar nodulus is vascularized by the medial branch of the posterior inferior cerebellar artery, which also supplies the uvula, tonsil, tuber, and pyramid of the vermis, and the inferior part of the cerebellar hemisphere, making isolated cerebellar nodulus infarction extremely rare. CPN occurs after a change in head position with respect to gravity and is caused by pathologies involving the vestibulo-cerebellar pathways. CPN is rarely seen in isolation. Additional neurological signs and ocular motor abnormalities are generally present.

Methods: A 62-year-old man was admitted to the emergency department with acute-onset positional vertigo and CPN as the sole finding on examination. Cranial magnetic resonance imaging revealed an acute infarction involving the nodulus. Results: Infarcts restricted to nodulus can cause positional vertigo and CPN without any associated neurological signs or ocul ar motor abnormalities.

Conclusion: Though very rare, cerebellar nodulus stroke must be searched in patients with positional vertigo of acute onset and isolated CPN on examination.

中央位置性眼球震颤可能是小脑结节梗死的唯一表现形式
目的:引起人们对急性位置性眩晕和中央位置性眼球震颤(CPN)的重视:提请注意急性位置性眩晕和中央位置性眼球震颤(CPN)是小脑结节梗死的唯一特征:背景:小脑结节由小脑后下动脉内侧支形成血管,该动脉还供应悬雍垂、扁桃体、小结节、蚓部金字塔和小脑半球下部,因此孤立的小脑结节梗死极为罕见。小脑结节发生于头部相对于重力的位置改变之后,是由前庭-小脑通路病变引起的。CPN 很少单独出现。一般还伴有其他神经系统体征和眼球运动异常:一名 62 岁的男子因急性发作性位置性眩晕和 CPN 作为唯一的检查结果被送入急诊科。头颅磁共振成像显示急性脑梗塞累及结节。结果:局限于小脑结节的梗塞可引起位置性眩晕和心律失常,但不伴有任何神经系统体征或眼球运动异常:结论:小脑结节卒中虽然非常罕见,但对于急性发作的位置性眩晕和检查时发现孤立的 CPN 的患者,必须加以警惕。

期刊介绍: The Neurologist publishes articles on topics of current interest to physicians treating patients with neurological diseases. The core of the journal is review articles focusing on clinically relevant issues. The journal also publishes case reports or case series which review the literature and put observations in perspective, as well as letters to the editor. Special features include the popular "10 Most Commonly Asked Questions" and the "Patient and Family Fact Sheet," a handy tear-out page that can be copied to hand out to patients and their caregivers.
