Abstract
Disseminated herpes simplex virus (HSV) is a known fatal condition in neonates and immunocompromised patients. However, very few cases have been reported in an immunocompetent host. We report a 1-year-old female child who presented to a children's hospital in Riyadh, Saudi Arabia, in 2022. She was previously healthy and presented with febrile illness associated with decrease conscious level. Upon examination, the patient had markedly elevated liver enzymes. A cerebrospinal fluid (CSF) polymerase chain reaction (PCR) finding of HSV as well as positive HSV IgM serology resulted in a diagnosis of disseminated HSV (encephalitis/hepatitis). She received acyclovir course and during follow-up for 1 year showed excellent developmental outcome.
