Papilloedema secondary to venous sinus thrombosis following glomus jugulare tumour surgery

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.Method:We present a case report and a review of the world literature concerning glomus jugulare tumours and cerebral venous sinus thrombosis.Case report: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.Conclusion: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.

Case report of glomus jugulare tumour associated with a posterior fossa cyst

A subgroup of complex glomus jugulare tumours exists. This includes: multiple, giant or neuropeptide-secreting lesions; those associated with other lesions, such as dural arterio-venous malformation or an adrenal tumour; and tumours in which there has been previous treatment with adverse outcome. To our knowledge, we present the first case of a glomus jugulare tumour associated with a posterior fossa cyst. This entity should be included in the subgroup of complex glomus jugulare tumours.

Glomus jugulare tumour presenting with isolated accessory nerve palsy

Glomus tumours of the skull base are rare, and most frequently present with symptoms of hearing loss and tinnitus. Diagnosis is often delayed due to the slow growth of the tumour. We describe the previously unreported occurrence of a glomus tumour presenting with a unilateral accessory nerve palsy.
