Rationale:
This article reports a case of coronavirus disease (COVID-19)-associated autoimmune encephalitis (AE) and reviews the relevant literature to investigate the clinical manifestations, auxiliary inspection, diagnosis and treatment, and prognosis of AE associated with COVID-19.
Patient Concerns:
A 68-year-old female with fatigue developed altered consciousness after 2 days of fever, thereafter testing positive for COVID-19. The protein levels in the lumbar puncture cerebrospinal fluid were elevated, and cranial magnetic resonance imaging (MRI) scan indicated T2-weighted hyperintensity in the temporal lobe.
Diagnoses:
The patient was diagnosed with COVID-19-associated AE.
Interventions:
After admission, the patient received pulse steroid therapy with methylprednisolone. Additionally, gastric protection, blood glucose control, nutritional support, and other treatments were administered.
Outcomes:
The symptoms were significantly relieved by steroid pulse therapy. At the 3-month follow-up, the patient had recovered completely without any obvious discomfort.
Lessons:
The possibility of AE should be considered if neurological symptoms occur a few days after infection with COVID-19, with early diagnosis and immediate steroid pulse therapy resulting in better outcomes.
