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 ...
Encephalitis; MRI scan image shows high signal in the temporal lobes and right inferior frontal gyrus in someone with herpes simplex encephalitis. Specialty: Neurology, infectious disease: Symptoms: Headache, fever, confusion, stiff neck, vomiting [1] Complications: Seizures, trouble speaking, memory problems, problems hearing [1] Duration
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 ...
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.
MRI of subject with eventual autopsy-proven LATE/LATE-NC. MRI scans are used to detect structural changes in the brain. In LATE, MRI may reveal severe atrophy in the medial temporal lobe, particularly in the hippocampus and amygdala, which are key areas affected by TDP-43 pathology, and may indicate hippocampal sclerosis.
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 ]
Frontotemporal lobar degeneration; Neuropathologic analysis of brain tissue from FTLD-TDP patients. Ubiquitin immunohistochemistry in cases of familial FTLD-TDP demonstrates staining of (a) neurites and neuronal cytoplasmic inclusions in the superficial cerebral neocortex, (b) neuronal cytoplasmic inclusions in hippocampal dentate granule cells, and (c) neuronal intranuclear inclusions in the ...
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.
