Неврологические осложнения нередко наблюдаются у пациентов с новой коронавирусной инфекцией. Среди них преобладают цереброваскулярные заболевания, встречаются поражения периферической нервной системы и спинного мозга различного характера, в том числе воспалительные и сосудистые миелопатии.

В настоящей статье приводится описание клинического случая миелопатии, ассоциированной с COVID-19, без структурных изменений спинного мозга при МР-визуализации с использованием стандартных импульсных последовательностей, однако визуализируемой с помощью спинальной МР-трактографии.</p></sec><sec><title>ЗАКЛЮЧЕЧНИЕ</title><p>ЗАКЛЮЧЕЧНИЕ. COVID-19 ассоциированная миелопатия – одно из характерных осложнений на фоне новой коронавирусной инфекции. Для верификации «МР-негативного» поражения центральной нервной системы при COVID-19 могут быть использованы расширенные протоколы МРТ-исследования, в том числе перспективный метод – магнитно-резонансная трактография.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>INTRODUCTION</title><p>INTRODUCTION. Neurological complications are often observed in patients with a new coronavirus infection. Cerebrovascular diseases prevail among them.
