The clinical findings of basilar dolichoectasia (DB) are caused by compression of the cranial nerves, vertebrobasilar ischaemia, hydrocephaly and compression of the brainstem. Hypoacusia as an isolated finding in DB is very rare.
We describe the case of a 48-year-old hypertensive man with bilateral hypoacusia as an isolated finding in DB. Diagnosis was made on MR, and arteriography showed changes characteristic of an anomalous blood vessel.
In patients with hypoacusia of uncertain aetiology, specially if they are also hypertensive, one should rule out the possibility of DB using cerebral magnetic resonance or angioresonance.
基底动脉延长扩张症(DB)的临床症状是由颅神经受压、椎基底动脉缺血、脑积水和脑干受压引起的。听力减退作为DB的孤立表现非常罕见。
我们描述了一名48岁高血压男性的病例,其双侧听力减退是DB的孤立表现。通过磁共振成像(MR)做出诊断,血管造影显示有异常血管的特征性改变。
对于病因不明的听力减退患者,特别是那些同时患有高血压的患者,应使用脑磁共振成像或血管磁共振成像排除DB的可能性。
