Key Takeaway:
- A 67-year-old man with post-traumatic asplenia developed severe varicella-zoster virus meningitis.
- The infection involved two cranial nerves: the facial nerve (VII) and the hypoglossal nerve (XII).
- The case highlights the potential for varicella-zoster virus to cause serious neurological complications.
A 67-year-old man with a history of traumatic spleen removal developed severe viral meningitis caused by the varicella-zoster virus, with complications affecting two cranial nerves, according to a case report published in Cureus.
The report describes an unusual presentation involving cranial nerve VII, which controls facial movement, and cranial nerve XII, which helps control tongue movement. The case highlights the potential for varicella-zoster virus infection to affect the nervous system beyond its more familiar skin symptoms.
Researchers Document an Unusual Neurological Presentation
Varicella-zoster virus causes chickenpox during initial infection and can later reactivate to cause shingles. In some cases, the virus can affect the central nervous system, leading to complications such as meningitis, an inflammation of the membranes surrounding the brain and spinal cord.
The patient’s history of post-traumatic asplenia the absence of a spleen following an injury was a notable part of the clinical presentation. The spleen plays an important role in the body’s defense against certain infections, although its absence does not establish the cause of this particular viral illness.
The report, titled “Severe Primary Varicella-Zoster Virus Meningitis With Dual Cranial Neuropathy (Cranial Nerve VII and Cranial Nerve XII) in a 67-Year-Old Man With Post-traumatic Asplenia: A Case Report,” documents the combination of meningitis and two cranial nerve complications in one patient.
Two Cranial Nerves Show Different Symptoms
Cranial nerve VII, also known as the facial nerve, controls facial expressions and contributes to functions including taste. Damage or dysfunction can cause facial weakness or paralysis, depending on the location and severity of the injury.
Cranial nerve XII, known as the hypoglossal nerve, controls most tongue movements. Dysfunction can interfere with tongue positioning and movement and may affect speech or swallowing.
The involvement of both nerves makes the case clinically notable because it illustrates how a viral infection can be associated with multiple neurological problems. However, a single case cannot establish how frequently these complications occur or determine whether the patient’s history of spleen removal increased his risk of this specific outcome.
Case Report Highlights the Need for Clinical Assessment
Meningitis can develop from viral, bacterial and other causes, and identifying the underlying infection is essential for appropriate treatment. Symptoms that may warrant urgent medical assessment include severe headache, fever, neck stiffness, confusion and new neurological changes.
Varicella-zoster virus can sometimes cause neurological complications even when the presentation differs from the typical rash associated with shingles. Clinicians may use a patient’s symptoms, neurological examination and laboratory testing, including analysis of cerebrospinal fluid, to investigate suspected viral meningitis.
The case report adds to the medical literature describing neurological complications associated with varicella-zoster virus. It does not, by itself, establish a new treatment recommendation or demonstrate that all patients with asplenia face an increased risk of this particular complication.
The findings also underscore the importance of distinguishing an unusual clinical observation from evidence that can be generalized to a broader population. Further research and additional documented cases would be needed to clarify the relationship between primary varicella-zoster infection, cranial neuropathy, and a history of traumatic asplenia.
