Sudden sensorineural hearing loss has a stablish etiology only in 10-15% of cases. Spontaneous intra-labyrinthine bleeding is a rare cause of sudden hearing and vestibular loss. The aim of this work is to provide useful and educational clinical information regarding this differential diagnosis, its treatment and prognosis. We present a case of sudden inner ear hypofunction caused by a labyrinthine hemorrhage, and discuss the literature on this topic. The literature search at “Medline” was performed with the Mesh terms “inner ear AND hemorrhage” and key-words “labyrinthine AND hemorrhage”. A 82-year old male patient, anti-coagulated, was admitted at our department with complaints of sudden right-ear hearing loss and dizziness. The clinical observation and complementary studies were suggestive of intra-labyrinthine bleeding. The more common causes of intra-labyrinthine bleeding are blood disorders, trauma and anti-coagulation drugs. The diagnosis is possible due to the notable advances in ear imaging through magnetic resonance. There is no specific treatment for this condition and the majority of cases are submitted to standard idiopathic sudden sensorineural hearing loss treatment with poor results as we can conclude in the published series.
