Introduction: Seizures related to metabolic disorders are common phenomena in many clinical contexts. However, clinical manifestations and neuroimaging findings in the context of a hyperglycemic crisis are less frequent phenomena with unclear pathophysiology.Case report: A 68-year-old man presented focal seizures and right homonymous hemianopsia after a non-ketotic hyperglycemic crisis. Brain MRI showed cortical diffusion restriction and subcortical T2 / FLAIR hypointensity in left occipital, temporal (mesial) and parietal lobes. Spectroscopy was performed showing a nonspecific pattern, cerebrospinal fluid was normal and there was improvement with glycemic control. MRI findings were considered secondary to the hyperglycemic crisis.Conclusion: Non-ketotic hyperglycemic states can manifest with several rare neurological alterations and recognizing them early is of vital importance given their potential reversibility. As in other metabolic disorders, epileptic seizures in this context can have focal-type characteristics. Although pathophysiological mechanisms are not clearly elucidated yet, multiple neuroimaging techniques promise to establish patterns that allow accurate and timely diagnosis.

Abstract Background We set out to investigate the characteristics and factors related to non-inflammation cerebrospinal fluid (CSF) and normal brain magnetic resonance images (MRI) of autoimmune encephalitis (AE) in patients. Methods The distribution and characteristics of brain MRI and CSF in 124 patients who were living with anti-NMDAR(71), LGI1(26),CASPR2(4),GABAR(23) encephalitis and who had been admitted between October 2016 and May 2018 were analyzed prospectively. Results 12 of the 124 patients(1%) had a normal MRI and non-inflammation CSF.Ten of them were LGI1(83%),while the remaining 1 patient was NMDAR(8.3%),1 patient was CASPR2(8.3%).The clinical symptoms including epilepsy, psychosis, cognitive disorders, conscious disorders, headache, faciobrachial dystonic seizure (FBDS), speech disorders and hypoventilation. AE with non-inflammation CSF and normal MRI with good clinical prognosis. The median modified Rankin Scale (mRS) was low, and recurrence rate was also low. Conclusion The clinical manifestations of on-inflammation CSF and brain MRI-negative patients with AE are not specific, but suggest a better prognosis and a lower recurrence rates.

Introduction: Anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis, a serious neurological autoimmune disorder caused by autoantibodies with diverse clinical manifestations, may simultaneously onset with antimyelin oligodendrocyte glycoprotein (MOG) demyelination after recurrent central nervous system (CNS) demyelination.Case Report: We present a case of anti-NMDAR encephalitis combining with anti-MOG CNS demyelination following recurrent CNS demyelination. A 38-year-old man admitted to hospital developed epileptic seizures following recurrent episodes of cross-sensory disturbance and dizziness. Magnetic resonance imaging (MRI) showed a demyelinating lesion in the right brainstem initially. Despite a good response to methylprednisolone pulse therapy at the beginning, the patient still had relapses and progression after corticosteroid reduction or withdrawal. Then brain MRI discovered new serpentine lesions involving extensive cerebral cortex on his second relapse. Repeat autoantibodies test indicated cerebrospinal fluid (CSF) NMDAR antibodies coexisted with MOG-Abs simultaneously, suggesting the diagnosis of anti-NMDAR encephalitis with anti-MOG CNS demyelination.Results: After a definite diagnosis, the patient was treated with mycophenolate mofetil (MMF) and corticosteroid. He was discharged after his symptoms ameliorated. No neurological sequels remained, and there were no effects on his activities of daily living after 6 months of immunoregulatory therapy of MMF and corticosteroid.Conclusion: For individuals with recurrent CNS demyelination, especially combining with cortical encephalitis, repeated detection of autoantibodies against AE, and demyelination in CSF/serum can be helpful to enable a definite early diagnosis. For patients who suffer from anti-NMDAR encephalitis combining with anti-MOG CNS demyelination, second-line immunotherapy is recommended when first-line treatment such as steroids, intravenous immunoglobulin G (IVIG) and plasma exchange has been proven ineffective to prevent the relapse of disease.

A 46-year-old previously healthy man presented with 1 week of headache, nausea, vomiting and dizziness. He was found to have cranial nerve deficits, his cerebrospinal fluid (CSF) demonstrated a lymphocytic pleocytosis and brain MRI suggested rhombencephalitis. Although Gram stains and cultures of his CSF did not identify a pathogen, Listeria monocytogenes DNA was detected by the FilmArray Meningitis/Encephalitis panel within 2 hours of performing a lumbar puncture. He was treated with ampicillin and gentamicin and had a near-complete recovery. This case highlights the importance of recognising L. monocytogenes infection as a cause of acute cranial nerve impairment with MRI findings suggestive of brainstem encephalitis. It also highlights the frequently atypical CSF profile and low yield of culture in L. monocytogenes rhombencephalitis and the value of multiplex PCR testing of CSF to rapidly identify this pathogen and permit targeted therapy.

There is increasing evidence of central nervous system involvement in numerous neuromuscular disorders primarily considered diseases of skeletal muscle. Our knowledge on cerebral affection in myopathies is expanding continuously due to a better understanding of the genetic background and underlying pathophysiological mechanisms. Intriguingly, there is a remarkable overlap of brain pathology in muscular diseases with pathomechanisms involved in neurodegenerative or neurodevelopmental disorders. A rapid progress in advanced neuroimaging techniques results in further detailed insight into structural and functional cerebral abnormalities. The spectrum of clinical manifestations is broad and includes movement disorders, neurovascular complications, paroxysmal neurological symptoms like migraine and epileptic seizures, but also behavioural abnormalities and cognitive dysfunction. Cerebral involvement implies a high socio-economic and personal burden in adult patients sometimes exceeding the everyday challenges associated with muscle weakness. It is especially important to clarify the nature and natural history of brain affection against the background of upcoming specific treatment regimen in hereditary myopathies that should address the brain as a secondary target. This review aims to highlight the character and extent of central nervous system involvement in patients with hereditary myopathies manifesting in adulthood, however also includes some childhood-onset diseases with brain abnormalities that transfer into adult neurological care.

Introduction: Cerebral Fat Embolism (CFE) is an underappreciated complication of trauma and orthopedic surgery whose diagnosis is mostly based on clinical suspicion. The utility of diagnostic testing is poorly defined. Methods: Using discharge diagnosis codes and a stroke database at a Level 1 Trauma Center, we performed a retrospective chart review of diagnostic workup and outcome for CFE from 2005 to 2019. Among those with a diagnosis of systemic fat emboli syndrome after long-bone fracture, cerebral involvement was established based on altered mental status, retinal findings, brain MRI findings or a combination of these. This report focuses on those who had MRI, all of which had findings of CFE. Results: Forty patients with CFE were identified, comprising 0.3% of all patients admitted with long-bone fractures. Of these patients, the average age was 39 years (SD 22), 30 (75%) were men, 28 (70%) had hypoxemia, 2 (5%) had petechial rash, and 29 (73%) were comatose, including 16 (40%) following orthopedic surgery. Brain MRI findings of CFE included scattered diffusion-restriction (60%), confluent white-matter edema (33%) and diffuse petechial hemorrhage (30%), with 27% having multiple findings of CFE. Ophthalmologic evaluation revealed exudates or hemorrhage suggestive of Purtscher-like retinopathy in 20 (91%) of 22 patients examined. Transcranial doppler microembolic signals (MES) were detected in 17 (53%) of 32 patients examined and were associated with scattered diffusion-restriction on MRI (chi square, p =0.01). Twelve patients (30%) died before discharge, 15 (38%) were discharged to a nursing facility, 12 (30%) to a rehabilitation facility and 1 (3%) to home. After a mean of 5.4 months, 1 patient had died, 11 had severe disability and 16 had moderate disability or better. Conclusion: The diagnosis of CFE is complicated by unknown sensitivity of diagnostic modalities. Nonetheless, typical MRI and ophthalmologic findings can assist in diagnosis. MES are associated with scattered infarction on MRI, suggesting active disease. The outcome of patients with CFE is highly variable, and a better understanding of this potentially devastating disease will require studies with larger numbers of cases collected in a standard fashion at multiple trauma centers.

Abstract Background Neurological manifestations are common in patients with COVID-19, but little is known about pathophysiological mechanisms. In this single-center study, we describe neurological manifestations of 58 patients, regarding cerebrospinal fluid (CSF) analysis and neuroimaging findings. Methods 58 COVID-19 patients with neurologic manifestations and SARS-CoV-2 RT-PCR screening on CSF analysis were included. Clinical, laboratory, and brain MRI data were retrospectively collected and analyzed. Results Patients were mostly men (66%) with a median age of 62 years. Encephalopathy was frequent (81%), followed by a pyramidal dysfunction (16%), seizures (10%), and headaches (5%). Protein and albumin levels in CSF were increased in 38% and 23%, respectively. A total of 40% of patients displayed an elevated albumin quotient suggesting impaired blood-brain barrier integrity. CSF-specific IgG oligoclonal band was found in five (11%) cases, suggesting an intrathecal synthesis of IgG, and 26 (55%) patients presented identical oligoclonal bands in serum and CSF. Four (7%) patients harbored a positive SARS-CoV-2 RT-PCR in CSF. Regarding brain MRI, 20 (38%) patients presented leptomeningeal enhancement. Conclusions Brain MRI abnormalities, especially leptomeningeal enhancement, and increased inflammatory markers in CSF are frequent in patients with neurological manifestations related to COVID-19, whereas SARS-CoV 2 detection in CSF remained scanty.

Background: Due to the difficulties in the definite diagnosis, data on brain imaging in pediatric patients with central nervous system (CNS)-invasive mold infection (IMD) are scarce. Our aim was to describe brain imaging abnormalities seen in immunocompromised children with CNS-IMD, and to analyze retrospectively whether specific imaging findings and sequences have a prognostic value. Methods: In a retrospective study of 19 pediatric patients with proven or probable CNS-IMD, magnetic resonance imaging (MRI)-findings were described and analyzed. The results were correlated with outcome, namely death, severe sequelae, or no neurological sequelae. Results: 11 children and 8 adolescents (11/8 with proven/probable CNS-IMD) were included. Seven of the patients died and 12/19 children survived (63%): seven without major neurological sequelae and five with major neurological sequelae. Multifocal ring enhancement and diffusion restriction were the most common brain MRI changes. Diffusion restriction was mostly seen at the core of the lesion. No patient with disease limited to one lobe died. Perivascular microbleeding seen on susceptibility weighted imaging (SWI) and/or gradient-echo/T2* images, as well as infarction, were associated with poor prognosis. Conclusions: The presence of infarction was related to poor outcome. As early microbleeding seems to be associated with poor prognosis, we suggest including SWI in routine diagnostic evaluation of immunocompromised children with suspected CNS-IMD.

We report a case of 40-year-old female who is known to have systemic lupus erythematosus (SLE) presenting with severe cognitive impairment with lymphopenia, proteinuria, and evidence of SLE serological activity. Initially, she was managed as a case of neuropsychiatric systemic lupus erythematosus (NPSLE) with Cyclophosphamide and pulse steroids. However, she has been deteriorating clinically in forms of right sided hemiparesis, blindness, and aphasia despite normalization of complements and anti-double stranded DNA antibodies levels. Diagnosis of progressive multifocal leukoencephalopathy (PML) was made based on her clinical manifestations with brain MRI findings of subcortical white matter lesions and detection of John Cunningham virus (JCV) in cerebrospinal fluid analysis. Immunosuppressive agents were discontinued aiming for immune system restoration.

Neurocutaneous Melanocytosis

Background: Neurocutaneous melanocytosis (NCM) is a poorly understood disease due to its rarity. This study aimed to summarize the characteristics of adult NCM and improve the awareness of this disease. Methods: The clinical data of 13 adult patients with NCM were retrospectively reviewed, including neuroimages, cerebrospinal fluid (CSF), and histological features. Results: There were 9 males and 4 females. The mean age at symptom onset was 36.5 years. The initial symptoms included intracranial hypertension in 8 patients and seizure in 4 patients. Ten patients had large and/or multiple congenital melanocytic nevi. MRI revealed hydrocephalus and diffuse thickening of the leptomeninges with T1 shortening in all patients. Post-contrast T1-weighted images showed diffuse linear enhancement of the leptomeninges. Lumbar punctures showed increased open pressure, and elevated protein levels and decreased glucose concentrations in CSF. Cells with intracytoplasmic coarse black granules were found in the CSF and were positive for S100, HMB45, and vimentin. Histopathology of the cutaneous lesions and meninges showed melanocytes but no evidence of malignant melanoma. Conclusion: Adult NCM patients present a diversity of clinical manifestations. Brain MRI showing diffuse thickening of the leptomeninges with T1 shortening is useful in diagnosing NCM. Heterocellular melanin may be of great value for early diagnosis of NCM in challenging cases.
