Both infectious and non-infectious etiologies of acute encephalitis have been described, as well as their specific presentations, diagnostic tests, and therapies. Classic findings of acute encephalitis include altered mental status, fever, and new lesions on neuroimaging or electroencephalogram (EEG). We report an interesting case of a 61-year-old male with a history of diffuse large B-cell lymphoma with secondary involvement of the central nervous system (SCNS-DLBCL). He presented with acute encephalitis: altered mental status, fever, leukocytosis, neuropsychiatric symptoms, multiple unchanged brain lesions on computed tomography scan of the head, and EEG showed mild to moderate diffuse slowing with low-moderate polymorphic delta and theta activity...

In the last decades, increasingly robust experimental approaches have formally demonstrated that autoimmunity is a physiological process involved in a large range of functions including cognition. On this basis, the recently enunciated "brain superautoantigens" theory proposes that autoimmunity has been a driving force of cognitive evolution. It is notably suggested that the immune and nervous systems have somehow co-evolved and exerted a mutual selection pressure benefiting to both systems. In this two-way process, the evolutionary-determined emergence of neurons expressing specific immunogenic antigens (brain superautoantigens) has exerted a selection pressure on immune genes shaping the T-cell repertoire...

Multiple system atrophy (MSA) may be difficult to distinguish clinically from other disorders, particularly in the early stages of the disease. An autonomic-only presentation can be indistinguishable from pure autonomic failure. Patients presenting with parkinsonism may be misdiagnosed as having Parkinson disease. Patients presenting with the cerebellar phenotype of MSA can mimic other adult-onset ataxias due to alcohol, chemotherapeutic agents, lead, lithium, and toluene, or vitamin E deficiency, as well as paraneoplastic, autoimmune, or genetic ataxias...

Cancer treatment strategies based on immune stimulation have recently entered the clinical arena, with unprecedented success. Immune checkpoint inhibitors (ICIs) work by indiscriminately promoting immune responses, which target tumour-associated antigens or tumour-specific mutations. However, the augmented immune response, most notably the T cell response, can cause either direct neurotoxicity or, more commonly, indirect neurotoxic effects through systemic or local inflammatory mechanisms or autoimmune mechanisms...

The cerebellum is a vulnerable target of autoimmunity in the CNS. The category of immune-mediated cerebellar ataxias (IMCAs) was recently established, and includes in particular paraneoplastic cerebellar degenerations (PCDs), gluten ataxia (GA) and anti-GAD65 antibody (Ab) associated-CA, all characterized by the presence of autoantibodies. The significance of onconeuronal autoantibodies remains uncertain in some cases. The pathogenic role of anti-GAD65Ab has been established both in vitro and in vivo, but a consensus has not been reached yet...

BACKGROUND: Dementias are fairly slowly progressive degenerative diseases of brain for which treatment options are very less and carry a lot of burden on family and society. A small percentage of them are rapidly progressive and mostly carry a different course outcome. However, there are no definite criteria other than the time line for these patients. AIMS: The aim of this was to identify and categorize the causes and course of rapidly progressive dementias seen in our center...

Lung cancer is a common malignant tumor in clinic. Morbidity and mortality are the first place in cancer, which seriously threaten the health of human beings. Due to the lack of effective and specific screening methods, most patients were found already at an advanced stage, and often combined with bone, brain, liver, adrenal and other parts of the metastasis. Symptoms of patient resulted from the primary tumor, metastatic spread, or paraneoplastic syndrome commonly cause the medical attention. For the syndrome related to the distant metastatic spread as the first manifestation, diagnosis would be a challenge...

Paraneoplastic limbic encephalitis is an autoimmune syndrome characterized by the acute or subacute onset of encephalopathy, memory loss, confusion, temporal lobe seizures, and behavioral and mood changes. Although most patients with paraneoplastic limbic encephalitis have antineuronal antibodies, advances in the field now permit the diagnosis without autoantibody test results. In this case illustrating the new diagnostic criteria, we report a 70-year-old woman who was brought to the emergency room after the acute onset of cognitive impairment, altered mental status, and choreoathetoid movements...

Usually limbic encephalitis (LE) is a paraneoplastic neurologic syndrome. LE symptoms can precede cancer even by a few years. Almost 50% of LE cases are connected with small cell lung carcinoma. Testis and breast cancers, granulomatous disease, thymoma, and teratomas are also often connected with LE. Other cases have infectious and autoimmunological aetiology. In LE limbic system dysfunction is observed, and it is accompanied by cerebellum and brain stem abnormalities as well as polyneuropathy. Paraneoplastic limbic encephalitis is sometimes a part of larger syndrome in which brain stem and spinal cord are involved in an inflammatory process called paraneoplastic encephalomyelitis...

Association of SIADH with malignancy was first reported in 1957, when it was described in two patients with bronchogenic carcinoma. While the association with small cell lung cancer (SCLC) is well known, that with non small cell lung cancer (NSCLC) has been rarely reported. We report a case of 70 year old male who was found to have hyponatremia secondary to SIADH. Radiological tests revealed right hilar lung mass with mediastinal adenopathy. Bronchoscopic biopsy revealed non-small cell lung cancer of type squamous cell...

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...

Antibodies against brain proteins were identified in the plasma of cancer patients and are defined to cause paraneoplastic neurological syndromes. The profiles of brain-directed antibodies in non-small cell lung cancer (NSCLC) are largely unknown. Here, for the first time, we compared autoantibodies against brain proteins in NSCLC (n = 18) against those present in age-matched non-cancer control subjects (n = 18) with a similar life-style, habit, and medical history. Self-recognizing immunoglobulin (IgG) are primarily directed against cells in the cortex (P = 0...

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...

Differential diagnosis of acute and subacute transverse myelopathy includes inflammatory, infectious, vascular, metabolic and paraneoplastic etiologies. Information on the diagnostic approach to transverse myelopathy with regard to daily clinical practice is provided. The differentiation between five lesion patterns on magnetic resonance imaging (MRI) in myelitis may be helpful: (1) longitudinal extensive transverse myelitis, (2) short segment ovoid or peripherally located, (3) "polio-like", (4) granulomatous and (5) segmental with rash...
