CNS lymphoma consists of 2 major subtypes: secondary CNS involvement by systemic lymphoma and PCNSL. Contrast-enhanced MR imaging is the method of choice for detecting CNS lymphoma. In leptomeningeal CNS lymphoma, representing two-thirds of secondary CNS lymphomas, imaging typically shows leptomeningeal, subependymal, dural, or cranial nerve enhancement. Single or multiple periventricular and/o...

conclusions: high percentage of hemolysins, biofilm and beta lactamase production by isolated staphylococci, suggests an important role of these virulence factors in the pathogenesis of isolated staphylococci from dermatitis lesions. the s. aureus isolates from wound infections, show a high sensitivity pattern to all examined antibiotics. only ciprofloxacin was found to be active against all is...

Parkinson's disease (PD) is not a simple movement disorder induced just by loss of dopaminergic neurons in the substantia nigra pars compacta. Apparently, the substantia nigra is not the only or the first brain region damaged in PD. Moreover, older and recent studies have shown that the degenerative process in PD is much more extensive and affects not only the central nervous system (CNS) but a...

BACKGROUND AND PURPOSE Iron oxide-based contrast agents have been investigated as more specific MR imaging agents for central nervous system (CNS) inflammation. Ferumoxtran-10 is a virus-size nanoparticle, taken up by reactive cells, that allows visualization of the phagocytic components of CNS lesions. Ferumoxtran-10 was compared with standard gadolinium-enhanced MR images in this exploratory ...

Some patients ultimately diagnosed with primary CNS lymphoma (PCNSL) have transient symptomatic contrast enhancing lesions. These "sentinel lesions" of PCNSL recede spontaneously or with corticosteroid treatment and present an important diagnostic dilemma because they show variable, but non-diagnostic histopathological features. Four previously healthy, immunocompetent patients aged 49 to 58 ye...

Although an estimated 40 million Americans have been infected with Histoplasma capsulatum [1], CNS involvement is rare except in the disseminated form. Lesions of the CNS have been reported to occur in nearly one fourth of the documented cases of disseminated histoplasmosis [2], but only in a few cases has the infection solely involved the CNS [3, 4]. This article details the cranial CT and spi...

Increasing use of neuroimaging in children has led to more incidental findings of CNS mass lesions, the management of which is uncertain. The authors' aims in this study are to describe these mass lesions and their evolution, as well as to discuss the management options and determine the prevalence of incidental CNS mass lesions at their pediatric clinic. A retrospective study was undertaken in...
