Paracoccidioidomycosis is the most common systemic mycosis in Latin America. Central nervous system (CNS) involvement described 10-27%. The objective to present two male patients with neuroparacoccidioidomycosis admitted Department of Internal Medicine National Hospital, one 2017 and other 2021. Both presented neurological symptoms improvement lesions amphotericin B. granulomas brain cells PCM ...
Astrocytoma as one of the most common central nervous system (CNS) tumors is rarely reported in veterinary literature. A 7-year-old Persian Lori-Bakhtiari ewe was presented to the clinic with a two months history of progressive blindness, nystagmus to the right, bilaterally decreased pupillary reflexes, head pressing and paddling. At necropsy, a whitish well-circumscribed mass with dimensions o...
Studies of lentiviral infections of various animals and man have shown that all may invade the CNS and induce pathological lesions. This is well established in infections with VV, CAEV, SIV, HIV-1, and FIV. Although VV and CAEV do not cause an overt immunodeficiency, they share several features pertinent for the establishment of neuropathologic lesions with those that induce immunodeficiency. T...
Interleukin (IL)-16, a CD4+ immune cell specific chemoattractant cytokine, has been shown to be involved in the development of multiple sclerosis, an inflammatory demyelinating disease central nervous system (CNS). While cells such as T and macrophages are reported producers IL-16, cellular source IL-16 CNS is less clear. This study investigates correlation expression levels with severity neuro...
BACKGROUND Vinblastine (VBL) is the standard treatment for systemic Langerhans cell histiocytosis (LCH), but little is known about its efficacy in central nervous system (CNS) mass lesions. METHODS A retrospective chart review was conducted. Twenty patients from the French LCH Study Group register met the inclusion criteria. In brief, they had CNS mass lesions, had been treated with VBL, and ...
The hypothalamus is susceptible to involvement by a variety of processes, including developmental abnormalities, primary tumors of the central nervous system (CNS), vascular tumors, systemic tumors affecting the CNS, and inflammatory and granulomatous diseases. The hypothalamus may also be involved by lesions arising from surrounding structures such as the pituitary gland. Magnetic resonance (M...
We examined the phenotype and function of cells infiltrating the central nervous system (CNS) of mice persistently infected with Theiler's murine encephalomyelitis virus (TMEV) for evidence that viral antigens are presented to T cells within the CNS. Expression of major histocompatibility complex (MHC) class II in the spinal cords of mice infected with TMEV was found predominantly on macrophage...
OBJECTIVE The study goal was to assess the benefits and potential limitations in the use of ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles in the MRI diagnosis of CNS inflammatory diseases and primary CNS lymphoma. METHODS Twenty patients with presumptive or known CNS lesions underwent MRI study. Eighteen patients received both gadolinium-based contrast agents (GBCAs) and 1 of ...
Human T-cell lymphotropic virus type 1 (HTLV-1) is associated with adult T-cell leukemia/lymphoma (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Only a limited percentage of infected individuals develop disease in response to the virus while the majority remain asymptomatic and HAM/TSP is the most common clinical manifestation of the virus. HAM/TSP is an inflamma...
Toxoplasmosis is an opportunistic infection caused by Toxoplasma gondii (TG), which affects one third of the global human population and commonly involves central nervous system (CNS)/brain despite so-called CNS immune privilege. Symptomatic clinical disease TG much more associated with immunodeficiency; clinicopathological manifestations toxoplasmosis are linked to individual responses includi...
