The case of a fourteen-year-old patient with Systemic Lupus Erythematosus with severe activity index and immunosuppressive treatment is described. He went to the Pediatric Emergency Department of the Carlos Andrade Marín Specialty Hospital, for presenting fever, headache, nausea, auditory hallucinations and paresis in the lower extremities. Cerebrospinal fluid was studied by Polymerase Chain Reaction, in which the presence of Human Herpes Virus type 6 or also called Roseolovirus was detected. Ganciclovir was started with a favorable clinical response in 72 hours. Conclusions: The presence of HHV-6 encephalitis should be considered in immunocompromised patients with encephalopathy and use of ganciclovir as directed therapy.
