Mumps, an acute viral infection characterised by parotid gland swelling, can lead to sensorineural hearing loss (SNHL) and vestibular symptoms. This report discusses a man in his early 30s who developed right-sided SNHL and vertigo 1 week after bilateral parotid swelling and orchitis. Elevated mumps IgM antibody titre confirmed the diagnosis. Audiometry revealed a profound hearing loss in the right ear. MRI showed fluid-attenuated inversion recovery hyperintensities in the right inner ear, indicating labyrinthitis. Despite treatment with oral and intratympanic corticosteroids, hearing did not improve, though vestibular symptoms resolved within a month. This case highlights the pathogenesis of mumps-induced inner ear involvement, aligning with previous studies indicating severe, often irreversible SNHL and transient vestibular symptoms due to viral endolymphatic labyrinthitis. Radiological findings supported the diagnosis, emphasising the importance of comprehensive evaluation in mumps-related complications.
流行性腮腺炎是一种以腮腺肿大为特征的急性病毒感染，可导致感音神经性听力损失（SNHL）和前庭症状。本报告讨论了一名30岁出头的男性，他在双侧腮腺肿大和睾丸炎1周后出现了右侧SNHL和眩晕。腮腺炎IgM抗体滴度升高证实了诊断。听力测试显示右耳有严重听力损失。MRI显示右内耳液体衰减反转恢复序列高信号，提示迷路炎。尽管使用了口服和鼓室内注射皮质类固醇进行治疗，但听力并未改善，不过前庭症状在1个月内得到缓解。该病例突出了腮腺炎引起内耳受累的发病机制，与先前的研究一致，这些研究表明病毒性内淋巴迷路炎可导致严重的、通常不可逆的SNHL和短暂的前庭症状。影像学检查结果支持了诊断，强调了在腮腺炎相关并发症中进行全面评估的重要性。
