Intracranial 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 ...
متن کاملIntracranial 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 کاملOptic nerve and choroidal circulation in glaucoma.
PURPOSE To investigate the circulation of the optic nerve head and choroid in patients with glaucoma. METHODS Laser Doppler flowmetry was used to determine optic nerve head relative blood velocity (ONVel), volume (ONVol), and flow (ONFlow) in 19 primary open-angle glaucoma patients and 15 age-matched healthy control subjects. In each subject, determinations were obtained from four sites on th...
متن کاملIntracranial penetrating injuries via the optic canal.
Two cases of intracranial penetration of a plastic or wooden chopstick via the optic canal are described. CT scans showed the chopsticks as linear hypodense structures in the suprasellar cistern contiguous with the optic canal. In one case, MR imaging was performed, which clearly depicted the foreign body and adjacent brain structures. Although they are extremely rare, transorbital intracranial...
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...
