Encephalitis with meningitis is known as meningoencephalitis, while encephalitis with involvement of the spinal cord is known as encephalomyelitis. [ 2 ] The word is from Ancient Greek ἐγκέφαλος , enképhalos 'brain', [ 37 ] composed of ἐν , en , 'in' and κεφαλή , kephalé , 'head', and the medical suffix -itis 'inflammation'.
Bickerstaff brainstem encephalitis is a rare inflammatory disorder of the central nervous system, [3] first described by Edwin Bickerstaff in 1951. [ 4 ] [ 5 ] It may also affect the peripheral nervous system , and has features in common with both Miller Fisher syndrome and Guillain–Barré syndrome .
B: T1-weighted MRI showing expansion of the brain infection 4 days later. Granulomatous amoebic encephalitis (GAE) [2] is a rare, often fatal, subacute-to-chronic central nervous system disease caused by certain species of free-living amoebae [3] of the genera Acanthamoeba, Balamuthia and Sappinia. [4] [5] The term is most commonly used with ...
Some may develop sleep disturbances and movement disorders. Anti-AMPAR encephalitis is paraneoplastic in etiology in 64% of cases, mostly associated with thymoma, ovarian teratoma and lung and breast cancer. Brain MRI shows T2 and FLAIR hyperintensities, particularly in the medial temporal lobe.
A FDG-PET scan of the brain may show abnormalities in cases when the MRI scan is normal. [29] EEG is abnormal in almost 90% of cases and typically shows general or focal slow wave activity. [30] CSF analysis often shows inflammatory changes with increased levels of white blood cells, total protein and the presence of oligoclonal bands. [31]
Rasmussen syndrome or Rasmussen's encephalitis is a rare inflammatory neurological disease, characterized by frequent and severe seizures, loss of motor skills and speech, hemiparesis (weakness on one side of the body), encephalitis (inflammation of the brain), and dementia.
Herpes simplex encephalitis; Other names: Herpes encephalitis, Herpesviral encephalitis: Coronal T2-weighted MR image shows high signal in the temporal lobes including hippocampal formations and parahippocampal gyrae, insulae, and right inferior frontal gyrus. A brain biopsy was performed and the histology was consistent with encephalitis. PCR ...
EEG shows periodic complexes with high-voltage diphasic waves occurring synchronously throughout the recording. CT or MRI may show cortical atrophy or white matter lesions. CSF examination usually reveals normal pressure, cell count, and total protein content; however, CSF globulin is almost always elevated, constituting up to 20 to 60% of CSF ...
