Chronic recurrent isolated vertigo is an uncommon manifestation of vertebrobasilar ischaemia. We report a 43-year-old female with 12-month history of recurrent attacks of isolated vertigo who presented with acute pontine infarctions. Clinical examination and vestibular function testing showed bilateral vestibular hypofunction affecting the horizontal and posterior semicircular canals and right saccule. Diffusion-weighted magnetic resonance imaging (MRI) demonstrated acute bilateral pontine infarcts and significant vertebrobasilar stenoses. The findings of recurrent isolated vertigo and bilateral vestibular hypofunction should not prevent a search for vertebrobasilar ischaemia, particularly in the presence of vascular risk factors.
慢性复发性孤立性眩晕是椎基底动脉缺血的一种不常见表现。我们报告一名43岁女性，有12个月复发性孤立性眩晕发作史，出现急性脑桥梗死。临床检查和前庭功能测试显示双侧前庭功能减退，累及水平半规管、后半规管和右侧球囊。弥散加权磁共振成像（MRI）显示急性双侧脑桥梗死和明显的椎基底动脉狭窄。复发性孤立性眩晕和双侧前庭功能减退的表现不应妨碍对椎基底动脉缺血的检查，尤其是在存在血管危险因素的情况下。
