Various cysts associated with intraorbital and intracranial portions of the optic nerve have been described. Arachnoid cysts of the optic nerve in association with optic nerve glioma were described by Wolter and McKenney (I964); Holt (I966) described two cases of cysts of the intracranial portion of the optic nerve, and Smith, Hoyt, and Newton (I969) also described cysts of the anterior third o...

Introduction: Demyelination is one of the main causes of neurological disability. It is the end product of numerous pathological processes, multiple sclerosis (MS) being the most common cause. More than 70% of the MS patients suffer from optic disturbances. This disease commonly affects the optic pathway, particularly the optic nerves and chiasm. Several attempts have been made to produce a ...

Optic nerve sheath meningiomas and optic nerve gliomas can be difficult to differentiate by computed tomography (CT). Three patients with optic nerve sheath meningiomas were studied with a CT/T 8800 scanner with 1.5-mm-thick axial sections and intravenous contrast material. In each case, an abnormal optic nerve sheath was identified by CT. A soft-tissue mass arose from one side of the sheath in...

INTRODUCTION Neurofibromatosis type 1 (NF1) is the most common neurocutaneous disease, nevertheless the number of publications providing clinical and genetic data from a significant number of children is limited. MATERIAL AND METHODS The available clinical, epidemiological, radiological and genetic data from 239 children with NF1, who attended at a specialist NF1 clinic between January 2011 a...

Chordoid glioma of the third ventricle is a rare and challenging tumor to surgery because of its unique anatomical location and its close juxtaposition to the neurovascular structures and hypothalamus. The authors report a case of chordoid glioma of the third ventricle in a 43-year-old woman, who presented with headache and somnolence. The tumor was approached by endoscopic transnasal technique...

MRI quantification of cranial nerves such as anterior visual pathway (AVP) in MRI is challenging due to their thin small size, structural variation along its path, and adjacent anatomic structures. Segmentation of pathologically abnormal optic nerve (e.g. optic nerve glioma) poses additional challenges due to changes in its shape at unpredictable locations. In this work, we propose a partitione...

BACKGROUND Malignant optic gliomas are rare, but they rapidly become lethal visual pathway tumors. We present the clinical course, treatment, and prognosis of a case of unilateral malignant optic glioma in a young man with a history of brain glioblastoma multiforme (GBM). CASE PRESENTATION A 21-year-old man, who had GBM 7 years ago complained of a transient shadow in his vision and presented ...
