Abstract:
Hypertrophic pachymeningitis is a rare inflammatory condition characterized by the thickening of the dura mater. We describe a patient who presented with intractable headache and complex cranial nerve palsy. Hypertrophy of the frontal dura was accompanied by pleocytosis and detection of Epstein-Barr virus (EBV) by PCR in cerebrospinal fluid. Clinical symptoms gradually improved after acyclovir and corticosteroid treatment, whereas dural pathology remained unchanged on neuroimaging. This case points at an expansion of the spectrum of neurological manifestations for EBV.
Insights
A rare inflammatory condition, hypertrophic pachymeningitis, thickened the dura mater in a patient with headache and cranial nerve palsy. Epstein-Barr virus (EBV) was detected, and symptoms improved with treatment, expanding the known neurological effects of EBV.
Area of Science:
- Neurology
- Infectious Diseases
- Neuroinflammation
Background:
- Hypertrophic pachymeningitis is a rare dural thickening condition.
- Intractable headache and cranial nerve palsy are significant neurological symptoms.
Observation:
- A patient presented with severe headache and cranial nerve deficits.
- Neuroimaging revealed frontal dural hypertrophy.
- Cerebrospinal fluid showed pleocytosis and positive Epstein-Barr virus (EBV) PCR.
Findings:
- Epstein-Barr virus (EBV) was identified as a potential cause of hypertrophic pachymeningitis.
- Acyclovir and corticosteroid treatment led to clinical symptom improvement.
- Dural pathology on imaging did not significantly change despite clinical recovery.
Implications:
- This case expands the spectrum of neurological manifestations associated with Epstein-Barr virus (EBV).
- Highlights the importance of considering viral etiologies in inflammatory pachymeningitis.
- Suggests a potential role for antiviral therapy in specific EBV-related neurological cases.
