Longitudinal Extensive Transverse Myelitis due to Varicella-Zoster Virus Infection in an Undiagnosed HIV-Positive Patient.

Infection is one of the critical causes of transverse myelitis. When a patient presents with skin shingles along with myelopathy, varicella-zoster myelitis should be considered, and the patient should be evaluated in terms of immune system dysfunction. Treatment with acyclovir has been shown to be effective in reducing clinical symptoms in such cases.
