Intracranial optic nerve angioblastoma.
Angiomatous tumours causing visual disturbances are well known (Reese, 1963). The tumour may be isolated (mainly in the orbit and choroid), or it may be a manifestation of von Hippel's disease (in the retina and on the optic disc), Sturge-Weber's disease (in the choroid and intracranial), or Coats's disease (in the retina). Angiomatous tumours of the optic nerve are extremely rare. This communi...
متن کاملIntracranial hypoglossal nerve schwannoma with extracranial extension
Benign extramedullary tumours of the foramen magnum region are largely schwannomas and meningiomas. Tumours originating from the motor part of cranial nerves, such as the VIIth, IXth, XIth and XIIth cranial nerves, are extremely rare. Hypoglossal nerve (cranial nerve XII) schwannomas are such an example, usually arising intracranially and, in exceptional cases, extending into the extracranial c...
متن کاملOptic nerve ultrasound for the detection of raised intracranial pressure.
BACKGROUND Optic nerve ultrasonography (ONUS) may help identify raised intracranial pressure (ICP). The optimal optic nerve sheath diameter (ONSD) cut-off for the identification of intracranial hypertension has not been established, with some clinical studies suggesting a higher cut-off than may be expected on the basis of prior laboratory investigation. OBJECTIVE To validate ONUS performed b...
متن کاملOptic nerve sheath decompression for the treatment of visual failure in chronic raised intracranial pressure.
The records of all patients undergoing optic nerve sheath decompression for visual failure in chronic raised intracranial pressure performed over a 15 year period have been reviewed. The aim was to study the visual outcome and relation to any shunting procedures. Fourteen patients (20 eyes) were identified in whom follow up information of at least one year was available. Eleven patients had ben...
متن کاملIntracranial extension of choroidal melanoma via the optic nerve.
A 62-year-old woman was treated with cyclocryotherapy for neovascular glaucoma of uncertain origin. Fifteen months later she was diagnosed as having a choroidal melanoma, which extended extrasclerally to fill the orbit and invaded the optic nerve intracranially to the chiasm. She was treated by orbital exenteration and neurosurgical resection of the intracranial portion of the optic nerve. The ...
