BACKGROUND: There is emerging evidence of an increased risk of venous thromboembolism as well as several reports of cerebral venous thrombosis in COVID-19. CASE PRESENTATION: A previously healthy man in his fifties was admitted due to sudden confusion and reduced consciousness. One month earlier the patient had symptoms with headache, fever, dry cough, vomiting and diarrhoea and reduced sense of taste and smell. He was diagnosed with COVID-19 and the symptoms were mainly resolved within three weeks. On admission the patient was disorientated with aphasia. Brain imaging revealed a haemorrhagic infarction in the left temporal lobe due to thrombosis of the left transverse sinus and low-molecular weight heparin was instituted. On follow-up four months later, there was clinical improvement with only slight problems with short term memory and concentration. INTERPRETATION: This case illustrates the risk of serious neurological complications due to cerebral venous thrombosis in COVID-19.
