BACKGROUND AND PURPOSE
Our purpose was to determine the frequency of abnormal findings on contrast-enhanced high-resolution MR imaging studies in patients with sudden hearing loss.
METHODS
Seventy-eight consecutive patients with sudden hearing loss underwent contrast-enhanced MR imaging of the temporal bone, cerebellopontine angle, and brain. Additional tests included audiologic examination, electrocochleography, fistula tests, and serologic tests for viral agents and autoimmune disorders.
RESULTS
Probable causes of the sudden hearing loss in these patients included viral or immune-mediated disease, Meniere disease, vascular disorder, syphilis, neoplasm, multiple sclerosis, and perilymphatic fistula. Twenty-four (31%) of the 78 patients were found to have abnormal imaging results early in the course of their work up and treatment.
CONCLUSION
The prevalence of abnormal findings on contrast-enhanced MR studies is higher than previously reported in patients with sudden hearing loss.
背景与目的
我们的目的是确定突发听力损失患者在对比增强高分辨率磁共振成像研究中异常发现的频率。
方法
78例连续的突发听力损失患者接受了颞骨、小脑脑桥角和脑的对比增强磁共振成像检查。其他检查包括听力学检查、耳蜗电图、瘘管试验以及针对病毒病原体和自身免疫性疾病的血清学检查。
结果
这些患者突发听力损失的可能原因包括病毒或免疫介导疾病、梅尼埃病、血管疾病、梅毒、肿瘤、多发性硬化和外淋巴瘘。在78例患者中，有24例（31%）在其检查和治疗过程早期被发现有异常影像学结果。
结论
对比增强磁共振研究中异常发现的患病率高于先前报道的突发听力损失患者。
