A Perfect Storm: Rare Concurrence of MeningoEncephalitis, Pneumonia, and Myocarditis Due to Varicella-Zoster Virus Infection in a Chronic Alcoholic Adult Male

Abstract Varicella-zoster virus (VZV), the cause of chickenpox, typically leads to a mild illness in children, but in adults—especially those with compromised immune systems or underlying risk factors like chronic alcoholism—it can result in severe complications. We describe the case of a 28-year-old man with a history of chronic alcohol use who presented with seizures and altered consciousness. On examination, he had a widespread vesicular rash characteristic of varicella. Further investigations revealed a rare combination of meningoencephalitis, myocarditis, and pneumonia, all attributed to VZV. His HIV test was negative, and there was no known contact with a recent varicella case. The patient was treated with intravenous acyclovir, corticosteroids, and comprehensive cardiopulmonary support in the intensive care unit. Over time, his condition steadily improved, culminating in full neurological recovery. This case highlights the potential for multi-organ involvement in adult varicella, particularly in vulnerable populations, and underscores the importance of early recognition and aggressive management.
