Axial fluid-attenuated inversion recovery MRI image demonstrating tumor-related infiltration involving lenticular nuclei (Arrow). Axial fluid-attenuated inversion recovery MRI image demonstrating tumor-related infiltration involving both temporal lobes (Short arrow), and the substantia nigra (Long arrow).
Additionally, temporal lobes with dense mononuclear cells can be observed infiltrating the meninges, and cerebellar herniation through the foramen magnum, [3] which leads to neurological symptoms like continuous circling or stroke-like seizures. [6] Attempts at proving a viral etiology have been unsuccessful. [5]
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'.
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 parahippogampal gyrae, insulae, and right inferior frontal gyrus. A brain biopsy was performed and the histology was consistent with encephalitis. PCR ...
Pug dog encephalitis (PDE) is an idiopathic inflammatory disease primarily affecting the prosencephalon (forebrain and thalamus). It is also known as necrotizing meningoencephalitis. The disease may be inherited in Pugs and Maltese and has been diagnosed in other breeds as well (Yorkies, Chihuahuas). [6] The prevalence of PDE in pugs is about 1 ...
Brain MRI is the mainstay of initial investigation pointing to limbic lobe pathology revealing increased T2 signal involving one or both temporal lobes in most cases. [ 22 ] [ 14 ] Serial MRI in LE starts as an acute disease with uni- or bilateral swollen temporomesial structures that are hyperintense on fluid attenuation inversion recovery and ...
Epstein-Barr virus encephalitis is usually accompanied by enlargement of the lymph nodes and enlargement of the spleen; Herpes zoster encephalitis may be accompanied by rash and skin vesicles, and because it involves the frontal lobe and temporal lobe, is often characterized by psychiatric features, memory deficits, and loss of language faculties.
Anti-NMDA receptor encephalitis is a type of brain inflammation caused by antibodies. [4] Early symptoms may include fever , headache, and feeling tired. [ 1 ] [ 2 ] This is then typically followed by psychosis which presents with false beliefs (delusions) and seeing or hearing things that others do not see or hear (hallucinations). [ 1 ]
