A major problem for neuroscientists and clinicians is why the central nervous system shows ineffective regeneration after injury. Injured peripheral nerve fibers reform their connections, whereas those in injured spinal cord never re-grow. Insights into the mechanisms for repair and restoration of function after spinal cord injury have been obtained by experiments showing that injured nerve cel...

background and objectives: multiple sclerosis (ms) is the most common demyelinating disease of the central nervous system with more than 5.2 million people across the world being afflicted with. magnetic resonance im­aging (mri) is a valuable tool in the diagnosis of ms. this study surveys the results of mri of the central nervous system and paranasal sinuses in the sample of ms patients in ker...

abstract background: a tumefactive lesion of central nervous system (cns) is defined as a mass-like lesion with a size greater than 2 cm in brain (magnetic resonance imaging) mri. neuroimaging may help to distinguish the nature of a tumefactive lesion and therefore can prevent an unnecessary brain biopsy. method: in this paper, we have emphasized on determining the nature of a cns tumefactive l...

=Abstract=A retrospective review of 22 cases of angiographically occult vascular malformations (AOVMs), treated at our institution during the past 6 years, was conducted to define better the clinical and radiological manifestations as well as the effective treatment modality of these lesions. There were 12 (54.5%) arteriovenous malformations (AVMs), 8 (36.4%)cavernous angiomas, 1 (4.5%) venous ...

ANGIOMATOUS tumours of the retina have been recognized and reported in the literature for many years. Although the first case was recorded by Panas and Remy (1879), and several others followed this publication, retinal angiomatosis was established as a clinical entity, presenting typically in infancy or early childhood, by von Hippel (1904) and was associated with angiomatosis of the central ne...
