Tullio phenomenon is a pattern of sound induced unsteadiness, imbalance or vertigo, associated with disturbances of oculomotor and postural control. As a possible cause of sudden sensorineural hearing loss, intralabyrinthine gross hemorrhage has been reported in subjects with bleeding tendency. We report a case of spontaneous intralabyrinthine hemorrhage followed by presentation of Tullio phenomenon. A 35-year-old man presented with sudden left side hearing loss and vertigo. Audiometry results indicated left total deafness and magnetic resonance images revealed left intralabyrinthine hemorrhage. At 1 month after hearing loss, sound and pressure-induced vertigo and disequilibrium newly developed. Follow-up images indicated signs of fibrosis in the left labyrinth and nystagmography results showed induction of nystagmus according to the stapedial reflex. This case suggests possibility of Tullio phenomenon in sudden sensorineural hearing loss patients.
