RationaleScrub typhus is a naturally occurring acute febrile disease caused by Orientia tsutsugamushi. Although it can cause multiple organ dysfunction, central nervous system infections are uncommon.Patient ConcernsA 17-year-old male presented with a 5-day history of fever and headaches. The MRI of the head revealed thickness and enhancement of the left temporal lobe and tentorium cerebelli, indicating potential inflammation.DiagnosesThe patient was diagnosed with a central nervous system infection.InterventionsCeftriaxone and acyclovir were administered intravenously to treat the infection, reduce fever, restore acid-base balance, and manage electrolyte disorders.OutcomesDespite receiving ceftriaxone and acyclovir as infection therapy, there was no improvement. Additional multipathogen metagenomic testing indicated the presence of O tsutsugamushi infection, and an eschar was identified in the left axilla. The diagnosis was changed to scrub typhus with meningitis and the therapy was modified to intravenous doxycycline. Following a 2-day therapy, the body temperature normalized, and the fever subsided.ConclusionsThe patient was diagnosed with scrub typhus accompanied by meningitis, and doxycycline treatment was effective.LessionRarely reported cases of scrub typhus with meningitis and the lack of identifiable symptoms increase the chance of misdiagnosis or oversight. Patients with central nervous system infections presenting with fever and headache unresponsive to conventional antibacterial and antiviral treatment should be considered for scrub typhus with meningitis. Prompt multipathogen metagenomic testing is recommended to confirm the diagnosis and modify the treatment accordingly.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
