BACKGROUND: Varicella-zoster virus (VZV) is a neurotropic alphaherpesvirus capable of causing a broad spectrum of neurologic complications beyond classic dermatomal herpes zoster. Although meningitis and encephalitis are well recognized manifestations of neuroinvasive VZV infection, associated autonomic dysfunction remains comparatively underreported, particularly in immunocompetent individuals.
CASE PRESENTATION: We describe a 66-year-old immunocompetent man who developed VZV meningoencephalitis associated with sacral dermatomal herpes zoster, urinary retention, and bowel dysmotility. Initial symptoms included fever, severe headache, photophobia, and low back pain, with delayed recognition of the characteristic sacral vesicular eruption. The patient subsequently developed encephalopathy and meningeal signs requiring intensive care unit admission. Cerebrospinal fluid analysis demonstrated lymphocytic pleocytosis and markedly elevated protein concentration, and VZV DNA was detected by polymerase chain reaction testing. During hospitalization, the patient developed severe urinary retention and gastrointestinal dysmotility without evidence of mechanical obstruction, raising concern for concurrent autonomic nervous system involvement. Following intravenous acyclovir therapy and supportive management, the patient experienced gradual neurologic and autonomic recovery.
CONCLUSIONS: This case highlights the potential for multifocal neuroinvasive VZV disease involving both central and autonomic nervous system structures in immunocompetent hosts. Clinicians should maintain awareness that urinary retention and bowel dysmotility may represent clinically significant autonomic manifestations of VZV reactivation, particularly in the setting of sacral dermatomal involvement.
