초록
Sudden hearing deterioration may occur in our population, but it is difficult to explain the exact pathophysiology and the cause. Magnetic resonance imaging (MRI) in sudden sensorineural hearing loss (SSNHL) is usually useful to evaluate neural lesions such as acoustic schwannoma and hemorrhage in labyrinth. Recently some cases of SSNHL caused by intralabyrintine hemorrhage were reported by the advance of MRI. In the case of intralabyrintine hemorrhage, MRI showed a hyperintense signal in the labyrinth on the pre-contrast and contrast enhanced T1-weighted image and relatively weak intensity on T2-weighted image. The prognosis SSNHL by intralabyrintine hemorrhage is generally known to be poor. We report a case of sudden deafness with intralabyrintine hemorrhage who has a history of anticoagulant administration, with a review of literature.
Abstract
Sudden hearing deterioration may occur in our population, but it is difficult to explain the exact pathophysiology and the cause. Magnetic resonance imaging (MRI) in sudden sensorineural hearing loss (SSNHL) is usually useful to evaluate neural lesions such as acoustic schwannoma and hemorrhage in labyrinth. Recently some cases of SSNHL caused by intralabyrintine hemorrhage were reported by the advance of MRI. In the case of intralabyrintine hemorrhage, MRI showed a hyperintense signal in the labyrinth on the pre-contrast and contrast enhanced T1-weighted image and relatively weak intensity on T2-weighted image. The prognosis SSNHL by intralabyrintine hemorrhage is generally known to be poor. We report a case of sudden deafness with intralabyrintine hemorrhage who has a history of anticoagulant administration, with a review of literature.
