Three-dimensional, fluid-attenuated inversion recovery (3D-FLAIR) of magnetic resonance imaging (MRI) has recently been developed to detect hemorrhage or high concentrations of protein. We present a patient with Ramsay Hunt syndrome, in whom high signals in the cochlear and vestibular apparatus were identified with 3D-FLAIR. The high signal areas in 3D-FLAIR were not detected by T1- and T2-weighted MRI in this case. This is the first report of high concentrations of protein in the inner ear in Ramsay Hunt syndrome using 3D-FLAIR, and suggests that high concentrations of protein in the inner ear are associated with hearing deterioration in some patients with Ramsay Hunt syndrome. 3D-FLAIR could be a useful diagnostic tool in the early stages of Ramsay Hunt syndrome.
磁共振成像（MRI）的三维液体衰减反转恢复序列（3D-FLAIR）最近已被开发用于检测出血或高浓度蛋白质。我们报告一例拉姆齐·亨特综合征患者，通过3D-FLAIR在其耳蜗和前庭装置中发现了高信号。在该病例中，T1加权和T2加权MRI未检测到3D-FLAIR中的高信号区域。这是首例使用3D-FLAIR检测拉姆齐·亨特综合征内耳中高浓度蛋白质的报告，提示内耳中高浓度蛋白质与部分拉姆齐·亨特综合征患者的听力减退有关。3D-FLAIR可能是拉姆齐·亨特综合征早期阶段有用的诊断工具。
