Mar 20, 2024 · Viral encephalitides are the result of brain parenchymal infection by a number of different viruses, many of which have similar presentations and imaging features. Specific diagnosis often requires PCR.
Feb 21, 2024 · Herpes simplex (HSV) encephalitis is the most common cause of fatal sporadic fulminant necrotizing viral encephalitis and has characteristic imaging findings. Two subtypes are recognized which differ in demographics, virus, and pattern of involvement.
Dec 14, 2018 · Cerebritis is essentially the same as encephalitis except that it is used to denote brain parenchymal inflammation secondary to infection with bacteria or other non-viral pathogens. In contrast, encephalitis usually is assumed to denote inflammation due to a virus or paraneoplastic/autoimmune process 1 .
Description of data. Eighty-five CT examinations from 68 patients and 101 MRI examinations from 80 patients with suspected encephalitis were assessed. Fifty-one patients had both a CT and MRI examination carried out, whereas 46 underwent either CT or MRI but not both.
Magnetic resonance imaging (MRI) findings may be nonspecific or specific and plays a major role in the diagnosis of encephalitis and predicting the possible cause. This pictorial essay reviews the MRI findings of common types of viral encephalitis.
Mar 20, 2024 · In this article, we illustrate the main radiological characteristics of autoimmune encephalitis and its subtypes, including the typical limbic presentation, the features of extra-limbic involvement, and also peculiar imaging findings.
Jan 1, 2023 · Autoimmune encephalitis is increasingly a diagnostic consideration in patients with subacute onset of memory loss, altered mental status, and/or psychiatric symptoms—core features of proposed diagnostic criteria. 1 Detection of autoimmune encephalitis is increasing over time with new neural autoantibody biomarker discovery and greater awareness among clinicians, although the diagnosis remains rare overall. 2 Diagnostic mimics of autoimmune encephalitis are far more prevalent than ...
Mar 19, 2017 · Imaging plays a role in the diagnosis of encephalitis when combined with the medical history, physical examination, serologic studies, and cerebrospinal fluid (CSF) analysis. In addition, there are multiple nonviral causes of infectious encephalitis including bacterial, fungal, parasitic, and rickettsial origins.
Jun 1, 2017 · The purpose of this article is to discuss the subset of immune-mediated CNS conditions with features of autoimmune encephalitis (ie, antibody-mediated inflammation of the brain), provide a framework for radiologists to understand the relevant neuroimmunology, review the major antibody subtypes, and describe the constellation of clinical and imag...
Jun 6, 2024 · Autoimmune encephalitis, also known as autoimmune limbic encephalitis, is an antibody-mediated brain inflammatory process. While typically involving the limbic system, any part of the brain or central nervous system more broadly, can be involved.
