Congruence and incongruence on the radiological and functional examination of inner ear hemorrhage

AbstractBackground Inner ear hemorrhage (IEH) is an increasingly recognized cochlear lesion that can cause sensorineural hearing loss (SNHL). Magnetic resonance imaging (MRI) is known to be the best imaging modality for clarifying the causes of SNHL and providing images that point to those causes.Aims Evaluate the lesional patterns in patients with presumed Inner ear hemorrhage (IEH) from radiological and functional aspects.Material and Methods We retrospectively reviewed 10 patients performed in our institution from 2014 to 2020, with suspected labyrinthine hemorrhage based on radiological and functional examination.Results We included 8 patients with IEH and sensorineural hearing loss (SNHL). The median age was 55 years (range: 3 months − 78 years). The results from the MRI and functional tests were compared for each end-organ. Only three cases (37.5%) showed a correlation between signal abnormalities and dysfunction in the labyrinthine apparatus.Conclusions In patients with SNHL inner ear hemorrhage needs to be ruled out in the differential diagnosis, so specific MRI sequences should be requested. It represents a way to a better understanding of the disorder and the variety of findings claim for a complete auditory and vestibular testing.Chinese abstract背景: 内耳出血(IEH)是一种被日渐认识的耳蜗病变, 可导致感音神经性听力损失(SNHL)。 磁共振成像 (MRI) 被认为是最好的成像方式来澄清 SNHL 的原因并提供指出这些原因的影像。目的: 从放射学和功能方面, 评估疑似内耳出血 (IEH) 患者的病变模式。材料和方法: 我们回顾性评价了 2014 年到 2020 年期间在我们机构接受治疗的 10 名患者。根据放射学和功能检查, 怀疑他们患有迷路出血。结果: 我们纳入了 8 名患有 IEH 和感音神经性听力损失 (SNHL) 的患者。 中位年龄为 55 年(范围: 3 个月 – 78 年)。 将每个末端器官 MRI 和功能测试的结果进行比较。 只有 3 例 (37.5%) 显示信号异常与迷路器官功能障碍。结论: SNHL 患者鉴别诊断时需排除内耳出血诊断, 因此应要求特定的 MRI 序列。 这样做可以更好了解该疾病及其有关各种发现, 并要求进行完整的听觉和前庭测试。Keywords: Inner ear hemorrhagesensorineural hearing lossvestibular disordermagnetic resonance imagingv-HITcVEMPSoVemps Disclosure statementNo potential conflict of interest was reported by the authors.
