Abstract

Human herpesvirus 6B (HHV-6B) encephalitis in a liver transplant recipient is rarely reported. In this report, we presented a case of HHV-6B encephalitis in a liver transplant recipient and reviewed the relevant literature. A 56-year-old man was admitted to the intensive care unit (ICU) with an acute headache and intermittent convulsion 17 days after liver transplantation. Next-generation sequencing (NGS) of the cerebrospinal fluid (CSF) revealed 30691 sequence reads of HHV-6B and real-time polymerase chain reaction (real-time PCR) of the CSF detected HHV-6B DNA at 12 000 copies/mL, so the patient was diagnosed with HHV-6B encephalitis and received ganciclovir treatment promptly. The condition of the patient improved well and returned to the general ward with no neurologic deficits. This case indicated that adequate awareness, early diagnosis, and timely treatment are crucial to a good prognosis of HHV-6B encephalitis after liver transplantation.
