Spontaneous subdural effusion in a hospitalized Covid-19 patient: Case report.

Subdural effusions (SE) have already been associated with several viruses, but there are few associations with Covid-19 reported to date, and all of them had one thing in common: the presence of superimposed bacterial rhinosinusitis. Here we describe the case of a 76-year-old male patient that was transferred to our center due to severe SARS-CoV-2 infection and developed a SE during hospital stay. He presented sensory level impairment during hospitalization, but an initial Head CT scan showed no alterations.
