突发性感音神经性听力损失（SSHL）与多种病因有关。然而，确定SSHL的确切原因仍然难以捉摸。最近的报道已经证明了磁共振成像在识别SSHL病变部位方面的有效性。本报告报告了一例68岁男性，其表现为右侧SSHL伴右侧面瘫。磁共振成像显示右侧桥下端t2加权图像上病灶区信号增强，提示术后水肿灶。磁共振成像在确定SSHL的病因方面变得越来越重要。讨论了听力损失病例的磁共振成像表现。
Sudden sensorineural hearing loss (SSHL) has been associated with many etiologies. However, determining the exact cause of SSHL remains elusive. Recent reports have demonstrated the usefulness of magnetic resonance imaging in identifying the site of lesion in SSHL. This report presents the case of a 68-year-old male who presented with right-sided SSHL associated with right-sided facial paralysis. Magnetic resonance imaging demonstrated a focal area of increased signal on T2-weighted image within the right inferior pons, suggestive of a postischemic edematous focus. Magnetic resonance imaging is becoming important in establishing the etiology of SSHL. Magnetic resonance imaging findings in cases of hearing loss are discussed.
