title: Papilloedema secondary to venous sinus thrombosis following glomus jugulare tumour surgery.
abstract: OBJECTIVE
  We present a case of a patient who had undergone embolisation and resection of a left glomus jugulare tumour, who presented three weeks post-operatively with magnetic resonance venography confirmed symptomatic cerebral venous sinus thrombosis.
  
  
  METHODS
  We present a case report and a review of the world literature concerning glomus jugulare tumours and cerebral venous sinus thrombosis.
  
  
  METHODS
  A 42-year-old man presented with blurred vision and reduced Snellen visual acuity just three weeks after glomus jugulare tumour surgery. Fundoscopy revealed bilateral haemorrhagic optic disc oedema. Urgent magnetic resonance venography confirmed a left lateral venous sinus thrombosis. It was felt that this was responsible for inadequate cerebrospinal fluid drainage, resulting in raised intracranial pressure and papilloedema.
  
  
  CONCLUSIONS
  To the authors' knowledge, this is the first account of a magnetic resonance venography confirmed venous sinus thrombosis and secondary papilloedema following glomus jugulare tumour surgery. Patients undergoing surgery involving resection or manipulation of the internal jugular vein may be at higher risk of developing thrombosis superior to the level of resection, and magnetic resonance venography ought to be considered an important diagnostic adjunct.
