Sudden onset of sensorineural hearing loss secondary to intralabyrinthine hemorrhage: MRI findings.

摘要

Sudden sensorineural hearing loss (SSHL) secondary to intralabyrinthine hemorrhage is rare. When it does occur, it may be caused by blood dyscrasias, sickle-cell disease, anticoagulation therapy, local trauma, leukemia, radiation therapy, or drug abuse; also, some cases are idiopathic.An audiogram determines whether an acute hearing loss is sensorineural, conductive, or mixed. Further evaluation should be carried out with computed tomography (CT), which is more sensitive in conductive hearing loss, and magnetic resonanceimaging (MRI), which is more sensitive in sensorineural hearing loss.5
