Our aim was to assess the effectiveness of imaging modalities in detecting the underlying pathologies in patients with pulsatile tinnitus.
Seventy-four patients with pulsatile tinnitus were radiologically evaluated. All patients except two are evaluated on a thin-section bone algorithm computed tomography scan covering the temporal bone and skull base, 14 patients with or without contrast-enhanced brain computed tomography, 7 patients with magnetic resonance imaging and magnetic resonance angiography, 5 patients with digital subtraction angiography, and 12 patients with Doppler ultrasonography.
The underlying pathology of tinnitus was detected in 50 patients (67.6%), and 24 patients were normal with radiologic studies. The most common cause was high jugular bulbus (21%) followed by atherosclerosis, dehiscent jugular bulbus, aneurysm of internal carotid artery, dural arteriovenous fistula, aberrant internal carotid artery, jugular diverticulum, and glomus tumor.
It was concluded that radiologic imaging methods are effective in detecting the underlying pathology of pulsatile tinnitus.
我们的目的是评估成像方式在检测搏动性耳鸣患者潜在病变方面的有效性。
对74例搏动性耳鸣患者进行了放射学评估。除2例患者外，所有患者均接受了覆盖颞骨和颅底的薄层骨算法计算机断层扫描评估，14例患者接受了有或无增强扫描的脑部计算机断层扫描，7例患者接受了磁共振成像和磁共振血管造影，5例患者接受了数字减影血管造影，12例患者接受了多普勒超声检查。
50例患者（67.6%）检测出耳鸣的潜在病变，24例患者经放射学检查结果正常。最常见的病因是高位颈静脉球（21%），其次是动脉粥样硬化、颈静脉球裂、颈内动脉动脉瘤、硬脑膜动静脉瘘、颈内动脉走行异常、颈静脉憩室和球瘤。
得出的结论是放射学成像方法在检测搏动性耳鸣的潜在病变方面是有效的。
