Human prion diseases, in common with other neurodegenerative diseases, may be sporadic or inherited and are characterized by the accumulation of cellular proteins accompanied by neuronal death and synaptic loss….
Prions are a rare cause of human disease but very important to recognize because of their potential for transmissibility and uniformly severe outcome. MR imaging plays an extremely important role…
The symptoms associated with slow viral or prion diseases of the central nervous system tend to have multiple neurologic symptoms, and different patients may present with different symptoms. This review…
The brain may be affected by a variety of abnormalities in association with HIV infection. Knowledge of these abnormalities and their characteristic imaging features is important to neuroradiologists for the…
Acute disseminated encephalomyelitis (ADEM) is a monophasic demyelinating disease of the central nervous system typically affecting the gray and the white matter of the brain and spinal cord in multiple…
Herpesviruses are one of the most common groups of pathogens causing central nervous system infections in humans. They mostly cause encephalitis, meningitis, or myelitis in immunocompetent and immunocompromised patients. Children,…
Encephalitis is an acute infection of brain parenchyma characterized clinically by fever, headache, and an altered level of consciousness. In the twenty-first century several outbreaks of encephalitis have been reported….
Many viral infections can involve the central nervous systems (CNS) of fetuses, neonates, infants, and children. The pathogenesis, patterns of CNS involvement, and species of viral infection may differ in…
Infections caused by enteroviruses, rabies, adenoviruses, and Nipah and Hanta viruses are discussed. Several studies defined the pattern of MR imaging findings in these disease processes that reflect parenchymal infiltration…
Many viral infections of the nervous system cause stereotyped pathologic features and overlapping clinical and imaging features. Neuroimaging usually offers neuroanatomical localization of the pathology, degree of involvement of the…
