title: Acute unilateral hearing loss as an early symptom of lateral cerebral sinus venous thrombosis.
abstract: BACKGROUND
  Increasing availability of neuroimaging has facilitated the diagnosis of cerebral sinus venous thrombosis(CSVT). However, CSVT may also present with unspecific or atypical symptoms, resulting in diagnostic delay.Single reports suggested otologic symptoms as such pitfalls.
  
  
  OBJECTIVE
  To screen patients with CSVT for otologic symptoms.
  
  
  METHODS
  Ten-year retrospective case series.
  
  
  METHODS
  Primary and tertiary care university clinic.
  
  
  METHODS
  Thirty-eight patients with CSVT.
  
  
  RESULTS
  Of 38 patients with CSVT, 3 individuals hadacute unilateral hearing loss, 2 of which also had concomitant tinnitus and headache, and were initially treated at the ear, nose, and throat department. Magnetic resonance imaging after hospital discharge showed ipsilateral thrombosis of the lateral venous sinus. Two female patients took oral contraceptives, 1 of whom also had a heterozygous factor V Leiden mutation.
  
  
  CONCLUSIONS
  Cerebral sinus venous thrombosis may present with unspecific symptoms such as acute unilateral hearing loss. If in conjunction with headache or risk factors for venous thrombosis, the suspicion of ipsilateral lateral CSVT should prompt rapid imaging including venography.
