Fatal Acute Necrotizing Encephalopathy in a 17-Year-Old Girl with COVID-19: A Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND Acute necrotizing encephalopathy (ANE) is a severe and rapidly progressive form of encephalopathy predominantly observed in children following various systemic infections. Although rare, cases of ANE have been increasingly associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This report details a fatal case of ANE in a 17-year-old girl diagnosed with coronavirus disease 2019 (COVID-19), emphasizing the critical need for early diagnosis and prompt intervention to improve clinical outcomes. CASE REPORT A previously healthy 17-year-old girl presented with a 3-day history of fever followed by onset of seizures and consciousness disorders after testing positive for SARS-CoV-2. Cranial magnetic resonance imaging (MRI) revealed bilateral symmetrical thalamus, which is a typical imaging presentation of ANE. Cerebrospinal fluid (CSF) examination revealed a normal cell count. Differential diagnoses such as acute disseminated encephalomyelitis (ADEM) and Leigh syndrome were excluded, leading to a diagnosis of ANE. Despite aggressive treatment, including respiratory support, intravenous immunoglobulin, and high-dose glucocorticoids, the patient's condition deteriorated rapidly, resulting in death the following day. CONCLUSIONS ANE is a rare but devastating condition in adolescents, particularly following viral infections such as COVID-19. It should be considered in patients presenting with seizures and progressive consciousness disorders after viral infection. Urgent neuroimaging and lumbar puncture are essential for diagnosis. Early recognition, immunotherapy, and aggressive management are crucial to mitigate the high mortality associated with this severe neurological disorder.
