Disseminated Varicella-Zoster Virus Infection Complicated by Encephalitis and Ramsay Hunt Syndrome in an HIV Patient

Varicella-zoster virus (VZV) is a human α-herpesvirus which cause primary varicella infection (chicken pox) or herpes zoster infection (shingles) after reactivation of the dormant virus. VZV infection is usually self-limited but disseminated infection can be seen in immunocompromised individuals. It can also get complicated by central nervous system (CNS) involvement. We describe a case of a 51-year-old male with human immunodeficiency virus (HIV) who presented with altered mental status and deficits in his right-sided cranial nerves of VI, VII, and VIII. The patient also had disseminated vesicular-pustular rash all over his body at different stages of healing. A diagnosis of disseminated VZV infection complicated by encephalitis and Ramsay Hunt syndrome was made and the patient was treated with intravenous acyclovir and oral prednisone with a rapid improvement. The coexistence of these conditions is rare. The purpose of this report is to increase awareness of the coexistence of these two conditions in HIV infected patients.
