Posterior reversible encephalopathy syndrome; Other names: Reversible posterior leukoencephalopathy syndrome (RPLS) Posterior reversible encephalopathy syndrome visible on magnetic resonance imaging as multiple cortico-subcortical areas of T2-weighted hyperintense (white) signal involving the occipital and parietal lobes bilaterally and pons.
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'.
PML is diagnosed in a patient with a progressive course of the disease, finding JC virus DNA in spinal fluid together with consistent white-matter lesions on brain magnetic resonance imaging (MRI); alternatively, a brain biopsy is diagnostic [1] when the typical histopathology of demyelination, bizarre astrocytes, and enlarged oligodendroglial ...
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 ...
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 ...
Ben Tarver, 29, began having seizures and panic attacks in September before exhibiting symptoms of paranoia. By the middle of October, he was diagnosed with Anti-NMDA Receptor Encephalitis, a rare ...
Herpes simplex encephalitis (HSE), or simply herpes encephalitis, is encephalitis due to herpes simplex virus. It is estimated to affect at least 1 in 500,000 individuals per year, [ 1 ] and some studies suggest an incidence rate of 5.9 cases per 100,000 live births.
Autoimmune encephalitis (AIE) is a type of encephalitis, and one of the most common causes of noninfectious encephalitis. It can be triggered by tumors , infections , or it may be cryptogenic . The neurological manifestations can be either acute or subacute and usually develop within six weeks.
