A Case of Labyrinthine Hydrops Caused by Spontaneous Intracranial Hypotension

Spontaneous intracranial hypotension (SIH) is a rare cause of labyrinthine hydrops. The otologic symptoms of SIH include ear fullness, tinnitus, and hearing loss which can result from labyrinthine hydrops. We report a case of labyrinthine hydrops caused by SIH, confirmed by an audiometric impairment that occurred only when in an upright posture.
