Post-infectious cerebellar ataxia following COVID-19 in a patient with epilepsy

Background

Various neurological manifestations have been described in relation to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and coronavirus disease 2019 (COVID-19). However, the development of cerebellar ataxia after recovery from COVID-19 is rare. We present a case of cerebellar ataxia 3 weeks after recovery from COVID-19.

Case Presentation

A 70-year-old male patient from an urban area of India presented with ataxia. He was hypertensive and had been receiving treatment for post-traumatic epilepsy for the previous 3 years. He had previously had laboratory-confirmed COVID-19 infection with mild symptoms that resolved within 2 weeks. However, 3 weeks after symptom improvement, he developed severe pan-cerebellar ataxia. Investigations were suggestive of post-infectious cerebellar ataxia. Other causes of ataxia were excluded. He responded well to pulse methylprednisolone therapy and was discharged with mild tremor and ataxia.

Conclusion

Post-infectious cerebellar ataxia is an unusual presentation after COVID-19. The clinician should be aware of such complications following COVID-19 infection as early diagnosis and proper management leads to better outcomes in many patients.
