Background: In a previous study on encephalitis lethargica, we identified an enterovirus in autopsy brain material. Transmission electron microscopy (TEM), immunohistochemistry (IHC) and molecular analysis were employed.  Our present objective was to investigate, using a similar approach, as to whether virus-like particles (VLP) and enterovirus antigen are present in Parkinson's disease (PD) brainstem neurons. Methods: Fixed tissue from autopsy specimens of late onset PD and control brainstem tissue were received for study...

Background: Neurolisteriosis ranks among the most severe neurological infections. Its radiological features have not been thoroughly studied. We aimed to describe the neuroradiological features of neurolisteriosis and assess their prognostic value. Methods: Patients with microbiologically-proven neurolisteriosis were enrolled from November 2009 to October 2013 in the nationwide MONALISA study. Magnetic resonance and computed tomography images were studied by two independent neuroradiologists...

BACKGROUND: Guillain-Barré syndrome (GBS), Miller Fisher syndrome (MFS) and Bickerstaff brainstem encephalitis (BBE) are a group of autoimmune neurological disorders (GBS spectrum disorder) that rarely recur. Recently, anti-ganglioside complex antibodies (GSC-Abs) were identified in patients with GBS spectrum disorder. However, there has been no case report describing GSC-Abs profiles in a recurrent case showing different phenotypes. CASE PRESENTATION: We report the case of a 33-year-old male patient with GQ1b-seronegative BBE-GBS after two prior episodes of MFS-GBS...

The recognition of the antibody-mediated encephalitis as a separate entity among the immune disorders of the central nervous system was one of the greatest breakthroughs of the last two decades in neurology. Unlike viral or tumor-related encephalitis, the antibody-mediated form has a good response to immunotherapy, which gives a special clinical importance to the discovery. Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is one of the first fully characterized antibody-mediated encephalitises. This article attempts to summarize the clinical features of this complex neuropsychiatric disorder with the aim to help its early recognition and to report the clinical course and the outcome of our six seropositive anti-NMDAR cases...

Encephalopathy is an important complication associated with influenza, most frequently observed in young children, with a wide range of severity. The most severe category of influenza-associated encephalopathy (IAE) is acute necrotizing encephalopathy (ANE), characterized by high frequency of neurologic sequelae and fatal outcomes. We report two young siblings who developed fever and seizures with altered mental status. Influenza A(H1N1)pdm09 virus infection was identified in upper respiratory tract specimens from both patients, and neuroimaging revealed bilateral inflammatory lesions, consistent with acute necrotizing encephalopathy...

Over the past few years, new-generation cell-based assays have demonstrated a robust association of autoantibodies to full-length human myelin oligodendrocyte glycoprotein (MOG-IgG) with (mostly recurrent) optic neuritis, myelitis and brainstem encephalitis, as well as with acute disseminated encephalomyelitis (ADEM)-like presentations. Most experts now consider MOG-IgG-associated encephalomyelitis (MOG-EM) a disease entity in its own right, immunopathogenetically distinct from both classic multiple sclerosis (MS) and aquaporin-4 (AQP4)-IgG-positive neuromyelitis optica spectrum disorders (NMOSD)...

BACKGROUND: Dengue fever is a common mosquito-borne viral illness with a clinical spectrum ranging from a simple febrile illness to potentially life-threatening complications such as dengue hemorrhagic fever and dengue shock syndrome. Dengue infection can affect many organs, including the central nervous system. The neurological manifestations reported in dengue infections are meningitis, encephalitis, stroke, acute disseminated encephalomyelitis, and Guillain-Barré syndrome. CASE PRESENTATION: We report the cases of two interesting patients with confirmed dengue infection who presented with complications of possible central nervous system vasculitis and cranial nerve palsy...

Brainstem encephalitis (BE) is a rare, severe, and potentially life-threatening inflammation of the central nervous system. Brainstem encephalitis has multiple etiologies, which vary in treatment and outcomes. The current literature is generally focused on the infectious causes of BE, while little is known about the other entities, including cases with inconclusive diagnoses. Additionally, the outcomes of BE are not well documented. We present a case of an 18-year-old male who presented with progressive symptoms of brainstem involvement...

We report the case of a patient who presented with progressive unsteadiness and narcoleptic attacks followed by behavioral change and psychosis, without visual disturbances or seizures. MRI revealed multiple areas of fluid attenuation inversion recovery (FLAIR) high-intensity lesions involving the cerebellum, brainstem, thalamus and third ventricular peri-ependymal region consistent with demyelination. Both the serum myelin oligodendrocyte glycoprotein-antibodies (MOG-Abs) and cerebral spinal fluid (CSF) anti-N-methyl-d-as-partate receptor (NMDAR) antibodies were positive using transfected cell based assays...

To facilitate the diagnosis of anti-NMDAR encephalitis presenting with brain lesions in unconventional locations (BLUL) on MRI, we retrospectively analyzed forty-five Chinese patients. Eighteen (40.0%) of their MRI initially exhibited one or more BLUL. These locations predominantly included cerebral gray matter (cortex, basal ganglia and thalamus), as well as white matter and brainstem. Due to these BLUL, thirteen (72.2%) patients were originally misdiagnosed with other diseases and developed poor clinical and imaging outcomes...

BACKGROUND: Brainstem encephalitis is the most common neurologic complication after enterovirus 71 infection. The involvement of brainstem, especially the dorsal medulla oblongata, can cause severe sequelae or death in children with enterovirus 71 infection. We aimed to determine the prevalence of dorsal medulla oblongata involvement in children with enterovirus 71-related brainstem encephalitis (EBE) by using conventional MRI and to evaluate the value of dorsal medulla oblongata involvement in outcome prediction...

Enterovirus A71 (EV-A71) infection has grown to become a serious threat to global public health. It is one of the major causes of hand, foot, and mouth disease (HFMD) in infants and young children. EV-A71 can also infect the central nervous system (CNS) and induce diverse neurological complications, such as brainstem encephalitis, aseptic meningitis, and acute flaccid paralysis, or even death. Viral proteins play a crucial role in EV-A71 infection. Many recent studies have discussed the structure and function of EV-A71 proteins, and the findings reported will definitely aid the development of vaccines and therapeutic approaches...

Bickerstaff's brainstem encephalitis (BBE) is a rare immune-mediated disorder characterized by ophthalmoplegia, ataxia and disturbance of consciousness, which may overlap with Guillain-Barré syndrome (GBS) if there is additional limb weakness. We report a 7-month-old boy presented with ophthalmoplegia followed by a rapidly ascending paralysis of all four limbs and disturbance of consciousness. The initial impression was BBE with overlapping GBS. This was supported by sequential nerve conduction study (NCS) findings compatible with an acute inflammatory demyelinating polyneuropathy (AIDP)...

We discuss the assessment and differential diagnoses of a middle-aged man who presented with trismus, double vision and behavioural problems. MRI scan of the brain was initially normal, but a month later showed high signal in the hippocampal region on fluid attenuated inversion recovery sequence (FLAIR) imaging. We suspected a paraneoplastic brainstem encephalitis because of his smoking history, rapidly progressive symptoms and abnormal brainstem signs. A positron emission tomography-CT scan identified abnormal subcarinal nodes, shown on biopsy to be metastatic small cell lung cancer...

Cluster of acute flaccid paralysis and cranial nerve dysfunction was associated with a 2014 outbreak of enterovirus D68 (EV-D68) respiratory illness in US. We describe a 33 year-old male patient of refractory dysphagia due to EV-D68-induced brainstem encephalitis successfully treated by surgery. Following acute upper respiratory tract infection, he developed dysphagia and bilateral facial paralysis. A coughing reflex was readily produced when the laryngopharyngeal fiberscope touched the epiglottis, however, water infusion induced only very weak and slow swallowing reflex, suggesting that only motor component was impaired but sensory function was preserved during swallowing...
