Acute meningoencephalitis associated with SARS-CoV-2 infection in Colombia.

We present the case of a patient in the third decade of life, with asthma as comorbidity, who presented to the emergency department due to odynophagia, dyspnea, and cough of 2 days of evolution, later developing acute ventilatory failure requiring orotracheal intubation. The high-resolution chest tomography study showed consolidation due to a pneumonic process towards the posterior segment of the right lower lobe with areas of ground-glass infiltrates with a peripheral distribution. During the clinical course, the patient presented multiple seizure episodes that met the criteria for status epilepticus with MRI compatible with changes due to leptomeningitis. Given symptoms and thorax imaging, tests for SARS-CoV-2 ensued, with both positive RT-PCR in bronchoalveolar lavage and cerebrospinal fluid for the virus also positive. RT-PCR multiplex panel of meningitis/encephalitis results negative for 14 common organisms. A diagnosis of acute meningoencephalitis associated with COVID-19 was considered, with an adequate response to corticosteroid management; to our knowledge, this is the first adult patient with CNS involvement and CSF positive test in Latin America.

Meningoencephalitis associated with COVID-19: a systematic review.

With the growing number of COVID-19 cases in recent times. significant set of patients with extra pulmonary symptoms has been reported worldwide. Here we venture out to summarize the clinical profile, investigations, and radiological findings among patients with SARS-CoV-2-associated meningoencephalitis in the form of a systemic review. This review was carried out based on the existing PRISMA (Preferred Report for Systematic Review and Meta analyses) consensus statement. The data for this review was collected from four databases: Pubmed/Medline, NIH Litcovid, Embase, and Cochrane library and Preprint servers up till 30 June 2020. Search strategy comprised of a range of keywords from relevant medical subject headings which includes "SARS-COV-2," "COVID-19," and "meningoencephalitis." All peer reviewed, case-control, case report, pre print articles satisfying our inclusion criteria were involved in the study. Quantitative data was expressed in mean ± SD, while the qualitative date in percentages. Paired t test was used for analysing the data based on differences between mean and respective values with a p < 0.05 considered to be statistically significant. A total of 61 cases were included from 25 studies after screening from databases and preprint servers, out of which 54 of them had completed investigation profile and were included in the final analysis. Clinical, laboratory findings, neuroimaging abnormalities, and EEG findings were analyzed in detail. This present review summarizes the available evidences related to the occurrence of meningoencephalitis in COVID-19.

Neurologic and neuroimaging findings in patients with COVID-19: A retrospective multicenter study.

OBJECTIVE: To describe neuroimaging findings and to report the epidemiologic and clinical characteristics of patients with coronavirus disease 2019 (COVID-19) with neurologic manifestations. METHODS: In this retrospective multicenter study (11 hospitals), we included 64 patients with confirmed COVID-19 with neurologic manifestations who underwent a brain MRI. RESULTS: The cohort included 43 men (67%) and 21 women (33%); their median age was 66 (range 20-92) years. Thirty-six (56%) brain MRIs were considered abnormal, possibly related to severe acute respiratory syndrome coronavirus. Ischemic strokes (27%), leptomeningeal enhancement (17%), and encephalitis (13%) were the most frequent neuroimaging findings. Confusion (53%) was the most common neurologic manifestation, followed by impaired consciousness (39%), presence of clinical signs of corticospinal tract involvement (31%), agitation (31%), and headache (16%). The profile of patients experiencing ischemic stroke was different from that of other patients with abnormal brain imaging: the former less frequently had acute respiratory distress syndrome (p = 0.006) and more frequently had corticospinal tract signs (p = 0.02). Patients with encephalitis were younger (p = 0.007), whereas agitation was more frequent for patients with leptomeningeal enhancement (p = 0.009). CONCLUSIONS: Patients with COVID-19 may develop a wide range of neurologic symptoms, which can be associated with severe and fatal complications such as ischemic stroke or encephalitis. In terms of meningoencephalitis involvement, even if a direct effect of the virus cannot be excluded, the pathophysiology seems to involve an immune or inflammatory process given the presence of signs of inflammation in both CSF and neuroimaging but the lack of virus in CSF.
