Spinal arteriovenous malformation masquerating zoster sine herpete

Area of Science:

• Neurology
• Vascular Surgery

Background:

• Zoster sine herpete (ZSH) is characterized by neuropathic pain without a rash, making diagnosis difficult.
• The absence of a rash in ZSH often leads to delayed diagnosis and increased risk of complications like postherpetic neuralgia.
• Misdiagnosis of ZSH is common, with other neuropathic pain conditions frequently mistaken for it.

Observation:

• This report details a rare case where a spinal arteriovenous malformation presented with symptoms mimicking Zoster sine herpete.
• The absence of a characteristic rash in ZSH complicates early and accurate diagnosis.

Findings:

• Spinal arteriovenous malformations can present atypically, mimicking neurological conditions like Zoster sine herpete.
• High clinical suspicion and thorough examination are crucial for diagnosing rare conditions that mimic common neurological disorders.

Implications:

• Early diagnosis of conditions mimicking ZSH, such as spinal arteriovenous malformations, is essential for effective treatment.
• Prompt intervention is critical to prevent potential neurological deficits and mortality associated with misdiagnosed or delayed diagnoses.
