Demyelinating lesions of fiber bundles in and adjacent to the hypothalamus (i.e. the fornix. anterior commissure, internal capsule, and optic system) may be the basis for autonomic and endocrine alterations in multiple sclerosis (MS) patients. Therefore we investigated the presence and immunological activity of lesions in hypothalamic fiber bundles of 17 MS patients and 14 controls. In the MS g...

Although previous studies have shown that the lesions of multiple sclerosis may involve the cerebral cortex, there is little published research on the prevalence and distribution of such lesions. Using neuropathological techniques and MRI, a series of studies has been undertaken in order to assess this, in particular to identify their relationship to cortical veins. A serial MRI study showed th...

Recent immunohistological and imaging studies emphasize the crucial role of axonal injury in determining the extent of permanent neurological deficits in patients with multiple sclerosis. We have recently shown that human immune cells are capable of producing the neurotrophin brain-derived neurotrophic factor (BDNF), which can prevent axonal and neuronal damage after various pathological insult...

Multiple sclerosis is a chronic inflammatory disease, which leads to focal plaques of demyelination and tissue injury in the CNS. The structural and immunopathological patterns of demyelination suggest that different immune mechanisms may be involved in tissue damage. In a subtype of lesions, which are mainly found in patients with acute fulminant multiple sclerosis with Balo's type concentric ...

introduction: multiple sclerosis (ms) is a demyelinating disease of the central nervous system (cns), affecting mostly young people at a mean age of 30 years. magnetic resonance imaging (mri) is one of the most specific and sensitive methods in diagnosing and detecting the evolution of multiple sclerosis disease. but it does not have the ability to differentiate between distinct histopathologic...

Tumefactive demyelinating lesions are a rare presentation of multiple sclerosis (MS). Diagnosis of tumefactive is commonly carried out using magnetic resonance image (MRI). Tumefactive diagnosis is difficult because of may similar to the clinical and MRI characteristics of glioma or a cerebral abscess. We presented a 35-years-old female with one episode of secondary generalized seizure after de...

We compared MRI criteria used to predict conversion of suspected multiple sclerosis to clinically definite multiple sclerosis. Seventy-four patients with clinically isolated neurological symptoms suggestive of multiple sclerosis were studied with MRI. Logistic regression analysis was used to remove redundant information, and a diagnostic model was built after each MRI parameter was dichotomized...

BACKGROUND AND PURPOSE Susceptibility MR imaging contrast variations reflect alterations in brain iron and myelin content, making this imaging tool relevant to studies of multiple sclerosis lesion heterogeneity. In this study, we aimed to characterize the relationship of high-field, susceptibility contrasts in multiple sclerosis lesions to clinical outcomes. MATERIALS AND METHODS Twenty-four ...
