Назальная ликворея приводит к потенциально смертельным осложнениям: менингит, менингоэнцефалит, пневмоцефалия, абсцесс мозга. Также при назальной ликвореи возможно возникновение менее опасных осложнений: аспирационного пневмонита и гастрита. В статье приводится случай аспирационного пневмонита у двух пациентов с назальной ликвореей, проходившими лечение в НМИЦН им. Н.Н. Бурденко во время пандемии COVID-19. Оба пациента отмечали профузный характер назальной ликвореи, жаловались на кашель в горизонтальном положении. В обоих случаях в ходе выполнения полимеразной цепной реакции РНК вируса (SARS-CoV-2) не обнаружена. Антитела (IgG, IgM) к коронавирусу не выявлены. На компьютерной томографии органов грудной клетки в обоих случаях выявлены участки затемнения по типу «матовое стекло». Так как данных за коронавирусную инфекцию не получено (отрицательные тесты на коронавирус, отсутствие антител), изменения в легких были интерпретированы как следствие постоянной аспирации ликвора. Пациентов госпитализировали в отдельную палату. Обоим пациентам проведена эндоскопическая эндоназальная пластика дефекта основания черепа. Послеоперационный период в обоих случаях протекал без особенностей. В обоих случаях пациенты выполнили через месяц компьютерную томографию органов грудной клетки. На снимках признаки поражения легочной ткани полностью регрессировали.</p></abstract><trans-abstract xml:lang="en"><p>Nasal liquorrhea — the outflow of cerebrospinal fluid from the cerebrospinal fluid spaces of the cranial cavity into the nasal cavity or paranasal sinuses due to the presence of a congenital or acquired defect in the bones of the skull base and meninges of various etiologies. Nasal liquorrhea leads to potentially fatal complications: meningitis, meningoencephalitis, pneumocephalus, brain abscess. Also, with nasal liquorrhea, less dangerous complications may occur: aspiration bronchopneumonia and gastritis. The article presents a case of aspiration pneumonitis in two patients with nasal liquorrhea treated at the N.N. N.N. Burdenko during the COVID-19 pandemic. Both patients noted the profuse nature of the nasal liquorrhea, complained of coughing in a horizontal position. In both cases, no RNA virus (SARS-CoV-2) was detected during the polymerase chain reaction. Antibodies (IgG, IgM) to coronavirus were not detected. Computed tomography of the chest organs in both cases revealed areas of frosted glass darkening. Since no data was obtained for coronavirus infection (negative tests for coronavirus, lack of antibodies), changes in the lungs were interpreted as a consequence of constant aspiration of cerebrospinal fluid. The patients were admitted to a separate ward. Both patients underwent endoscopic endonasal plasty of the skull base defect. The postoperative period in both cases was uneventful. In both cases, the patients underwent computed tomography scan of the chest organs one month later. On the photographs, the signs of pneumontis completely regressed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>назальная ликворея</kwd><kwd>дефект основания черепа</kwd><kwd>аспирационный пневмонит</kwd><kwd>основание черепа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nasal liquorrhea</kwd><kwd>skull base defect</kwd><kwd>aspiration pneumonitis</kwd><kwd>skull base</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Schlosser RJ, Woodworth BA, Wilensky EM et al.
