Sudden hearing deterioration may occur in our population, but it is difficult to explain the exact pathophysiology and the cause. Magnetic resonance imaging (MRI) in sudden sensorineural hearing loss (SSNHL) is usually useful to evaluate neural lesions such as acoustic schwannoma and hemorrhage in labyrinth. Recently some cases of SSNHL caused by intralabyrintine hemorrhage were reported by the advance of MRI. In the case of intralabyrintine hemorrhage, MRI showed a hyperintense signal in the labyrinth on the pre-contrast and contrast enhanced T1-weighted image and relatively weak intensity on T2-weighted image. The prognosis SSNHL by intralabyrintine hemorrhage is generally known to be poor. We report a case of sudden deafness with intralabyrintine hemorrhage who has a history of anticoagulant administration, with a review of literature.
在我们的人群中可能会发生突发性听力减退,但很难解释其确切的病理生理学和病因。磁共振成像(MRI)对于评估突发性感音神经性听力损失(SSNHL)中的神经病变(如听神经瘤和迷路出血)通常很有用。最近,随着MRI技术的进步,有一些关于迷路内出血导致SSNHL的病例报道。在迷路内出血的情况下,MRI在对比剂前和对比剂增强T1加权图像上显示迷路内有高信号,而在T2加权图像上信号相对较弱。一般认为,迷路内出血导致的SSNHL预后较差。我们报告一例有抗凝剂使用史且伴有迷路内出血的突发性耳聋病例,并对相关文献进行综述。
