Otogenic brain abscess and concomitant acute COVID 19 infection - case report and review of the literature.

Background: COVID-19 has attracted global attention primarily because of the severe acute respiratory symptoms associated with it. However, nearly one third of the patients also present with neurologic symptoms. This report describes a case of a previously healthy woman with acute COVID-19 infection, who developed acute facial nerve palsy and rapid progression to coma due to otogenic brain abscess.
Case Description: A 63-year-old woman with acute COVID-19 infection exhibited acute facial nerve paresis, high fever and purulent secretion from her left ear within 48 hours after COVID-19 onset. Cranial CT scan confirmed acute mastoiditis, precipitating an urgent mastoidectomy. A postoperative contrast-enhanced MRI on the same day revealed a subdural empyema, which prompted an urgent craniotomy and decompression. Intraoperative microbiological swabs confirmed a Streptococcus pyogenes infection, however RT-PCR was negative for SARS-CoV-2. After immediate i.v. antibiotic treatment, extubation was achieved four days post-operation, and the patient was discharged without neurologic deficits 19 days after postoperatively.
Conclusion: This finding adds a layer of insight into the specific nature of the infection, suggesting a potential absence of SARS-CoV-2 involvement in otogenic subdural empyema. However, the impact of SARS-CoV-2 in otogenic brain abscess cannot be excluded to date and should be further prospectively investigated. The complete recovery of neurological status, emphasizes the importance of prompt and interdisciplinary interventions in managing rare and severe complications associated with COVID-19.
