Analyses of the CSF and serum revealed anti SOX-1 antibodies at initial presentation but PCA-2 antibodies seven months after diagnosis. [ncbi.nlm.nih.gov]

Patients can express more than one autoantibody and present with more than one neuronal syndrome. [mdedge.com]

Some patients present more slowly with psychiatric manifestations. The MRI may be normal or may demonstrate medial temporal T2 hyperintensity. [ahcmedia.com]

Clinical presentation is variable but typically is gradual with short-term memory loss (anterograde memory impairment) and mental status changes. [radiopaedia.org]

• Mediastinal Lymphadenopathy

  After three cycles of therapy, he was re-evaluated with a chest computed tomography which showed a 50% reduction in the tumor mass and in the size of the hilar and mediastinal lymphadenopathy. [jmedicalcasereports.biomedcentral.com]

If a primary tumor is discovered during the workup, it should be removed and treated with the most up-to-date oncologic treatment available. [ncbi.nlm.nih.gov]

An extensive search for an underlying malignancy should be undertaken, guided by the type of antibody discovered on the workup. Most authorities recommend screening with whole body FDG-PET/CT. [ahcmedia.com]

Results of autoimmune workup revealed positive LGI1 antibody which is part of VGKC. That confirmed our diagnosis. [jneuro.com]

The limited stage of the disease, irrespective of anti-neuronal antibody status, is associated with neurological improvement after tumor treatment. The treatment of LE is generally unsatisfactory. [jmedicalcasereports.biomedcentral.com]

While it can cause severe neurological deficits or death in a substantial proportion of the patients, approximately one-third show neurological improvement and another 20 - 40% stabilize in response to treatment, including immunotherapy and/or tumor treatment [unboundmedicine.com]

Her seizures were refractory to treatment, and she was given pentobarbital to induce a coma. [mdedge.com]

A remarkable finding was the poor prognosis of patients with dysautonomia; a tumour was found in 37 out of 51 cases and in 28 of these the diagnosis followed the neurological syndrome with a median time of 4.6 months. [cordis.europa.eu]

Affected patients are often older and have an unfavorable prognosis. [paperity.org]

• Early diagnosis and treatment are associated with a better prognosis and decreased risk of relapse. • Treatment of the underlying disorder usually improves the movement disorders, but symptomatic treatment may be necessary as well. [medlink.com]

Further imaging to look for etiology revealed no evidence of any mass lesion, tumour or secondaries anywhere in the body. [jneuro.com]

In fact, viral etiology is the most frequent of encephalitis. However, among all viral factors there is one that is especially important in the case of EL, herpes simplex virus type 1 (HSV-1). [lifepersona.com]

Therefore, for the clinician, markers are important which on the one hand prove the paraneoplastic etiology of the given neurological syndrome, and on the other hand help to diagnose the associated tumor. [degruyter.com]
