A 2 and a half year-old boy with neurofibromatosis developed unilateral proptosis, decreased visual acuity, and optic disk edema. After the discovery and removal of an optic nerve glioma, the patient had ten years of excellent health until he began having headaches, nausea, and vomiting. He had
We report the case of a twelve-year-old boy who presented with visual impairment and headache and was found to harbour a purely intrasellar cystic pilocytic astrocytoma originating from proximal left optic nerve. The mass was explored transcranially and decompression of the optic apparatus and
BACKGROUND
Arachnoid proliferation, although rare, is known to occur in association with optic gliomas. However, chondroid and chordoid metaplasia has not been reported previously.
METHODS
A 27-year-old male presented with progressive, painless loss of vision in right eye, associated with vomiting
A 3 1/2-year-old girl with a huge optic glioma was reported. On February 26, 1978, she was hospitalized for signs of increased intracranial pressure, namely headache, vomiting and consciousness disturbance. Before admission she did not complain of her visual disturbance. A huge mass lesion in the
BACKGROUND
The coexistence of glial high grade tumors (glioblastoma, anaplastic astrocytoma) and cerebral aneurysms is common but the association with optic glioma is rare. The treatment of these associated lesions is problematic.
METHODS
A 36-year-old white woman presented to our institution with
OBJECTIVE
To report a case illustrating the value of pattern VEP and pattern ERG (PERG) in monitoring optic nerve gliomata (OG).
METHODS
A 15-year-old girl presented with a 3-year history of frontal headaches and a 5-month history of blurred vision in the right eye. MRI scanning revealed a
We report a 63-year-old, previously healthy female patient with glioblastoma multiforme of the optic nerve and chiasm presenting as acute anterior optic neuropathy. She presented with a 3-week history of progressively increasing headaches, retrobulbar pain, rapidly progressive visual loss in the
We report the case of a 31-year-old male who presented to the ER with a 1-week history of progressively worsening, throbbing, left retro-orbital headache, ptosis, and subjective worsening of short-term memory function. Initial review of systems and laboratory data were noncontributory.
OBJECTIVE
To investigate the clinical feature of the chronic compressive optic neuropathy without optic atrophy.
METHODS
Retrospective cases series study. The clinical data of 25 patients (37 eyes) with chronic compressive optic neuropathy without optic atrophy, treated in Beijing Tongren Eye
Neurofibromatosis type 1 (NF1) is an autosomal dominantly inherited familial tumor syndrome. Benign tumors such as pilocytic astrocytoma, optic glioma make up the majority of intracranial neoplasms in patients with NF1. There have only been a handful of cases in which adult glioblastoma presented
The effect of radiosurgery on optic gliomas is uncertain. We report two cases of low-grade glioma of the optic nerve and chiasm treated by transcranial subtotal removal and Gamma Knife radiosurgery. The first case was a 2-year-old boy, admitted with visual disturbance and nystagmus.
To present a case of glioblastoma multiforme which initially presented with only ophthalmic manifestations.A 48-year-old man presented with decreased vision and pain with eye movements of the right eye. MRI of the brain showed increased T2/FLAIR signal Idiopathic sclerosing inflammation of the orbit is a distinct form of orbital inflammatory disease characterized by slow and relentless involvement of orbital structures. It is this insidious and relentless course that makes distinction from neoplastic lesions clinically difficult. We report the
BACKGROUND
Medulloepithelioma is a rare congenital tumor of the primitive medullary neuroepithelium. A significant proportion of patients with medulloepithelioma arising from the optic nerve die from intracranial spread or cerebral metastasis. Because it has no known distinct clinical features and
Magnetic resonance imaging disclosed both optic nerve tortuosity and kinking in a 64-year-old man with orbital pain and monolateral abducens nerve palsy. The association between optic nerve tortuosity and abducens nerve palsy is often described in literature reports of idiopathic intracranial
