Cytomegalovirus Encephalitis in an Allogeneic Hematopoietic Cell Transplant Recipient: A Case Report and Review of Literature

Ganciclovir and foscarnet dual-therapy for cytomegalovirus encephalitis: A case report and review of the literature

Cytomegalovirus (CMV) is a ubiquitous herpesvirus which establishes lifelong latency following primary infection. It is then capable of reactivating in the face of immunosuppression. Encephalitis is a less common, but particularly devastating syndrome associated with CMV. Here, we describe a case of CMV encephalitis in an allogeneic hematopoietic stem cell transplant recipient who received dual antiviral therapy with ganciclovir and foscarnet. The case presentation is followed by a summary of cases reported in the last ten years, with the goal of describing vulnerable patient populations, treatment courses, and outcomes. Finally, the discussion includes a review of the literature, with a focus on diagnostic criteria and the role for dual antiviral therapy in CMV encephalitis.
