The paraneoplastic limbic encephalitis is a rare disease. It is caused by the presence of autoantibodies creating an inflammatory reaction of the predominant brain parenchyma in the meso-temporal lobe and in other parts of the limbic system. Its presence requires looking for an underlying tumour. The management of this paraneoplastic syndrome includes an immunosuppressive therapy in addition to the treatment of the underlying tumour. However, the management of this disease is not yet standardized.

Paraneoplastic limbic encephalitis (PLE), a paraneoplastic neurological syndrome (PNS), is a rare nervous system disorder that results from the indirect effects of tumors and is commonly associated with small-cell lung cancer (SCLC). Previous studies have reported that magnetic resonance imaging (MRI) may be useful for diagnosing LE. Temporal lobe abnormalities are observed using T2-weighted and fluid-attenuated inversion recovery sequences; however, such abnormalities are detected in only 60% of patients with PLE...

OBJECTIVE: The increasing incidence of new-onset seizures with age is well known. Often, the etiology cannot be clarified. In the present study, patients with unprovoked late-onset seizures and without known neoplasm, who might have had paraneoplastic encephalitis, were investigated for a potentially underlying autoimmunity. METHODS: Sixty-six consecutive patients (36 women; aged ≥55 years) after having at least one seizure or seizures for ≤6 months were prospectively identified over a period of 4...

Inflammatory mechanisms have been increasingly implicated in the origin of seizures and epilepsy. These mechanisms are involved in the genesis of encephalitides in which seizures are a common complaint. Experimental and clinical evidence suggests different inflammatory responses in the brains of patients with epilepsy depending on the etiology. In general, activation of both innate and adaptive immunity plays a role in refractory forms of epilepsy. Epilepsies in which seizures develop after infiltration of cells of the adaptive immune system in the central nervous system (CNS) include a broad range of epileptic disorders with different (known or unknown) etiologies...

Limbic encephalitis (LE) is an autoimmune or paraneoplastic disease that affects the medial temporal lobes. The patient will usually present with cognitive impairment, psychiatric changes, and seizures. Autoimmune limbic encephalitis (LE) is a challenging diagnosis as it is not always included in the typical paraneoplastic/autoimmune panels. Anti-GAD antibodies are associated with various disease including type I diabetes mellitus, various autoimmune processes, some neoplastic and infectious diseases. Thus, it is not as specific as some of the antibodies causing LE...

PURPOSE OF REVIEW: This article reviews the spectrum of neurologic complications associated with lymphoma, leukemia, and paraproteinemic disorders. While leptomeningeal metastasis is the most common complication of lymphoma and leukemia and peripheral neuropathy is the most common complication of paraproteinemic disorders, clinicians need to be familiar with the diverse neurologic complications of these disorders. RECENT FINDINGS: Lymphomatous nervous system involvement can be difficult to diagnose, especially when it is the presenting symptom...

Checkpoint inhibitors are increasingly being used in the treatment of malignant melanoma and other cancers. With the use of such therapies, autoimmune-mediated adverse events in the central and peripheral nervous system are likely to occur more frequently. We report a unique case of brainstem encephalitis with a sudden lethal outcome following ipilimumab and pembrolizumab therapy in a patient with malignant melanoma. The autopsy showed a diffuse nodular activation of microglia in the whole encephalon with prominent intraparenchymal and perivascular lymphocytic infiltration of the brainstem...

Onconeural antibodies are associated with cancer and paraneoplastic encephalitis. While their pathogenic role is still largely unknown, their high diagnostic value is undisputed. In this study we describe the discovery of a novel target of autoimmunity in an index case of paraneoplastic encephalitis associated with urogenital cancer.A 75-year-old man with a history of invasive bladder carcinoma 6 years ago with multiple recurrences and a newly discovered renal cell carcinoma presented with seizures and progressive cognitive decline followed by super-refractory status epilepticus...

BACKGROUND: Given that psychiatric symptoms are common, not only during the course of the illness but also on presentation, in children and adolescents with anti-N-methyl-d-aspartate receptor encephalitis, it is important that practitioners possess an adequate understanding of the clinical features and potential treatment of this disease. We describe the clinical characteristics of 24 patients who presented to the California Encephalitis Project. METHODS: Patients were referred by physicians, and standardized forms were used to gather demographic, clinical, and laboratory data...

Biotherapy represents an innovative therapeutic approach that includes immunotherapy (vaccines, apheresis, and antibodies); gene therapy; and stem cell transplants. Their development helps to cross the bridge from bench to bedside and brings new hope of a cure for severe diseases in different fields of medicine. In neurology, a growing range of applications is being developed for these medications. Valuable results are now available in the field of autoimmunity, neuro-oncology, paraneoplastic manifestations, and neurodegenerative disorders...

Paraneoplastic limbic encephalitis (PLE) is a rare disorder infrequently accompanying malignancy, coexisting in ~50% of the cases with small-cell lung cancer (SCLC). The pathomechanism of PLE is considered to be immune-mediated, with production of specific anti-Hu antibodies and activation of T-cells directed against onconeural antigens present on both tumor cells and neurons. We herein report the case of a 50-year-old male patient who, prior to being diagnosed with SCLC, presented with typical symptoms of PLE (seizures, subacute cognitive dysfunction with severe memory impairment, anxiety and hallucinations)...

BACKGROUND: Immune cross-reactivity between malignant and normal tissues causes the rare, so called paraneoplastic syndrome (PS). In approximately 60% of the patients, various onconeural antibodies are detectable in the cerebrospinal fluid (CSF) and are associated with typical tumour entities. METHODS: We report an unusual case of paraneoplastic limbic encephalitis (PLE) in a 17-year-old adolescent with classical Hodgkin lymphoma. RESULTS: He presented with a variety of neurologic and neuropsychiatric symptoms, profound B-symptoms and typical MRI findings including hyperintense lesions with contrast enhancement in the medial temporal lobe and limbic system...

There are common aspects and mechanisms between different types of autoimmune diseases such as multiple sclerosis (MS), neuromyelitis optica spectrum disorders (NMOSDs), and autoimmune encephalitis (AE) as well as paraneoplastic inflammatory disorders of the central nervous system. To our present knowledge, depending on the disease, T and B cells as well as antibodies contribute to various aspects of the pathogenesis. Possibly the events leading to the breaking of tolerance between the different diseases are of great similarity and so far, only partially understood...

Anti-NMDAR (N-methyl-D-aspartic acid receptor) encephalitis, first described in 2007, is a rare, autoimmune limbic encephalitis. In half of the cases anti-NMDAR antibodies are paraneoplastic manifestations of an underlying tumor (mostly ovarian teratoma). In the early stage of the disease psychiatric symptoms are prominent, therefore 60-70% of the patients are first treated in a psychiatric department. In most of the cases, typical neurological symptoms appear later. Besides the clinical picture and typical symptoms, verifying presence of IgG antibodies in the serum or CSF is necessary to set up the diagnosis...

Paraneoplastic neurological syndromes are rare autoimmune manifestations of malignancies associated with specific antibodies. Anti-Hu associated brainstem encephalitis, a well-described syndrome, usually presents subacutely with preferential involvement of the medulla. Anti-Hu antibodies target intraneuronal antigens and are therefore highly correlated with neurological syndromes when present concomitantly with a neoplasm. Reported is a case of anti-Hu brainstem encephalitis associated with a pancreatic neuroendocrine tumor (PNET) presenting with central hypoventilation...

Anti-N-methyl-d-aspartate receptor (NMDAR) limbic encephalitis is the most common form of paraneoplastic encephalitis that is associated with teratomas. Because tumor removal leads to better clinical outcomes, it is essential to reveal the location of the teratomas. This is the first reported case of anti-NMDAR encephalitis associated with teratoma of the fallopian tube. Salpingo-oophorectomy improved neurological symptoms and immunohistochemical examinations indicated the expression of NMDAR on neuroglial cells within the fallopian tube teratoma...

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a rare condition characterized by emotional and behavioral disturbances, dyskinesias, and extrapyramidal signs. It occurs in young women of reproductive age and is classically described as a paraneoplastic phenomenon. We present a 36-year-old, HIV-positive female who was admitted to the hospital in an acute confusional state, with a stiff posture, periods of motor agitation, and myoclonic jerks of the hands. Her mental state progressively deteriorated...
