Юноша поступил с жалобами на головную боль, рвоту, светобоязнь, гиперакузию. Известно, что в раннем возрасте он был прооперирован по поводу аномалии Арнольда – Киари, имел субдурально-перитонеальный шунт. За две недели до госпитализации перенёс новую коронавирусную инфекцию в лёгкой степени тяжести, которая была подтверждена положительным анализом мазка из ротоглотки методом полимеразной цепной реакции. Цефалгии носили острый характер, купировались кратковременно после применения анальгетиков. При осмотре лежал с закрытыми глазами, просил тишины и затемнения в палате. Любое движение головой сопровождалась головокружением, головной болью, рвотой. При объективном осмотре патологических изменений со стороны внутренних органов не обнаружено. В неврологическом статусе определялись светобоязнь, двоение в глазах, асимметричное лицо, асимметрия глазных щелей S &gt; D, опущение левого угла рта, нистагм, гиперакузия. Ригидности затылочных мышц нет. Менингеальные знаки отрицательные. Тазовых нарушений нет. По данным лабораторного обследования обнаружены лимфоцитопения, тромбоцитоз, ускорение скорости оседания эритроцитов, умеренное повышение ферритина, D-димеров. Проведённые методы нейровизуализации (мультиспиральная компьютерная томография головного мозга с внутривенным контрастированием, магнитно-резонансная томография головного мозга, ультразвуковая диагностика сосудов головного мозга) тромбов в интракраниальных и экстракраниальных сосудах не обнаружили. Выявлены низкопозитивные значения антител IgM к кардиолипину. По результатам полимеразной цепной реакции обнаружен полиморфизм G20210A в гене протромбина. В качестве лечения получал высокодозные глюкокортикоиды, гепарин. Несмотря на проводимую терапию через полтора месяца от момента госпитализации подросток умер от тромбоза центральных венозных синусов (кавернозного синуса слева, поперечных синусов, яремных вен), которые подтверждены на аутопсии. Данный клинический случай тромбоза венозного синуса у подростка в постковидном периоде представлял диагностические трудности, так как методы точной визуализации не обнаружили наличие тромба в церебральных сосудах.</p></abstract><trans-abstract xml:lang="en"><p>The article presents a case of a fatal outcome of a 15-year-old teenager with cerebral vascular thrombosis, which developed in the post COVID-19 period. The young man came in with complaints of headache, vomiting, photophobia, hyperacusis. It was known that at an early age he had been operated on for the Arnold – Chiari anomaly, had a subdural-peritoneal shunt. Two weeks before hospitalization, he suffered a new coronavirus infection of mild severity, which was confirmed by a positive analysis of a smear from the oropharynx by polymerase chain reaction. Cephalgia was acute, stopped for a short time after the use of analgesics. During the examination, the patient laid with his eyes closed, asked for silence and blackout in the ward. Any movement of the head was accompanied by dizziness, headache, vomiting. During an objective examination, no pathological changes were found on the part of the internal organs. The neurological status was determined by photophobia, double vision, asymmetric face, asymmetry of the eye slits S &gt; D, drooping of the left corner of the mouth, nystagmus, hyperacusis. There was no rigidity of the occipital muscles. Meningeal signs were negative. There were no pelvic disorders. According to the laboratory examination, lymphocytopenia, thrombocytosis, acceleration of ESR, moderate increase in ferritin, D-dimers were detected. Conducted neuroimaging methods (MSCT of the brain with intravenous contrast, brain MRI, ultrasound diagnostics of cerebral vessels) did not find any blood clots in intracranial and extracranial vessels. Low-positive values of IgM antibodies to cardiolipin were revealed. According to the results of polymerase chain reaction, polymorphism G20210A was detected in the prothrombin gene. The patient received high-dose glucocorticoids and heparin for treatment. Despite the therapy, a month and a half after hospitalization, the teenager died from thrombosis of the central venous sinuses (cavernous sinus on the left, transverse sinuses, jugular veins), which were confirmed on autopsy. This clinical case of venous sinus thrombosis in a teenager in the post COVID-19 period presented diagnostic difficulties, since accurate imaging methods did not detect the presence of a blood clot in the cerebral vessels.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>постковидный синдром</kwd><kwd>тромбоз</kwd><kwd>дети</kwd><kwd>мутация гена протромбина</kwd><kwd>антифосфолипидные антитела</kwd></kwd-group><kwd-group xml:lang="en"><kwd>post COVID-19 syndrome</kwd><kwd>thrombosis</kwd><kwd>children</kwd><kwd>prothrombin gene mutation</kwd><kwd>antiphospholipid antibodies</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">Cui S, Chen S, Li X, Liu S, Wang F.
