  • Abstract
  • Look Inside

 We reported a case of spontaneous intracranial hypotension in a 43-year-old woman. The patient complained of hearing loss and tinnitus in her right ear,dizziness and headache. Her cranial MRI with gadolinium infusion showed a diffuse enhancement of the whole dura mater,and her audiogram showed a low-tone sensorineural hearing loss of the right ear. Her complaints disappeared under conservative observation of 6 weeks after the initial symptom. This case suggested that low-tone sensorineural hearing loss and dizziness of the patients with spontaneous intracranial hypotension were caused by a relative endolymphatic hydrops resulting from a discharge of perilymphatic fluid through the cochlear aqueduct.
