The value of post-contrast delayed three-dimensional fluid-attenuated inversion recovery MRI in the diagnosis of unilateral vestibulopathy manifesting as episodic vestibular syndrome

Nearly half of the patients with UVP presenting with EVS had abnormal findings on 3D-FLAIR MRI, primarily showing vestibular EH and vestibular PE. Vestibular PE occurred more frequently in the acute phase of UVP, and was often accompanied by more severe vestibular function impairment. The presence of vestibular PE may be associated with ischemic and inflammatory mechanisms. The degree of vestibular EH was positively correlated with the severity of hearing impairment. CP value >49%, PTA >30 dB, and VRFs may help to predict abnormal MRI findings in UVP presenting with EVS.
