Acute diffuse edematous-hemorrhagic Epstein–Barr virus meningoencephalitis: A case report

INTRODUCTION: In this study, we presented a rare case of Epstein–Barr virus (EBV) meningoencephalitis presented with meningoencephalitis-like symptoms and diffuse edematous hemorrhage. PATIENT CONCERNS: A 77-year-old male patient was admitted to our hospital with fever, headache, confusion, and unconsciousness for 7 days. Physical examination revealed unconsciousness and stiffness of the neck. DIAGNOSIS: The final diagnosis was EBV meningoencephalitis. INTERVENTIONS: Ganciclovir (two times 350 mg/day, 21 days), methylprednisolone sodium succinate (120 mg, 5 days), and IV immunoglobulins (IV Ig) (0.4 g/kg, 5 days) were given to this patient. OUTCOMES: But the patient's clinical symptoms did not improve, and he was still in a coma. His family refused to be further diagnosed and discharged. After discharge for 2 months, the patient was in a coma. Four months later, the patient died of complications of pulmonary infection. CONCLUSION: The patient is an adult, and imaging was dominated by intracranial diffuse microhemorrhage and edema, which was different from the typical imaging characteristics of EBV encephalitis as previously reported. This specific imaging change may provide new clinical value for the diagnosis of EBV encephalitis.
