Enhanced MRI has recently become an even more useful diagnostic tool in the study of the labyrinth in sudden deafness and vertigo. A 22-year-old male who experienced a right-sided sudden deafness and vertigo due to mumps virus underwent labyrinthine MRI examination with gadolinium, and both labyrinthine and nerve bundle involvement was demonstrated. The relationship between mumps virus and the sudden deafness in humans has not been completely established and the path of labyrinthine infection and the possible eighth-nerve involvement is discussed. In vivo evidence of labyrinthine and cochleovestibular-nerve involvement, in mumps virus sudden deafness and vertigo has not been previously demonstrated. MRI findings may represent a new contribution in the evaluation of the etiopathogenesis of mumps virus deafness and vertigo.
增强磁共振成像（MRI）最近在突发性耳聋和眩晕的内耳研究中成为一种更有用的诊断工具。一名22岁男性因腮腺炎病毒导致右侧突发性耳聋和眩晕，接受了钆增强内耳MRI检查，结果显示内耳和神经束均受累。腮腺炎病毒与人类突发性耳聋之间的关系尚未完全明确，本文讨论了内耳感染途径以及可能的第八对脑神经受累情况。此前尚未有腮腺炎病毒导致突发性耳聋和眩晕时内耳及耳蜗前庭神经受累的体内证据。MRI检查结果可能为评估腮腺炎病毒致聋和眩晕的病因学作出新的贡献。
