Varicella-zoster virus meningitis after spinal anesthesia: A case report

Abstract

BACKGROUND Headache is a common complication of regional anesthesia. The treatment of post spinal anesthesia headache varies depending on the cause. Although meningitis is rare, it can cause significant harm to the patient. Post dural puncture headache and septic meningitis are the most commonly suspected causes of post spinal anesthesia headache; however, other causes should also be considered. CASE SUMMARY A 69-year-old woman was scheduled for varicose vein stripping surgery under spinal anesthesia. The procedure was performed aseptically, and surgery was completed without any complications. After 4 d, the patient visited the emergency room with complaints of headache, nausea, and anorexia. Clinical examination revealed that the patient was afebrile. Considering the history of spinal anesthesia, post dural puncture headache and septic meningitis was initially suspected, and the patient was treated with empirical antibiotics. Subsequently, varicella-zoster virus PCR test result was positive, and all other test results were negative. The patient was diagnosed with meningitis caused by varicella-zoster virus and was treated with acyclovir for 5 d. The headache improved, and the patient was discharged without any problems. CONCLUSION Viral meningitis due to virus reactivation may cause headache after regional anesthesia. Therefore, clinicians should consider multiple etiologies of headache.
