Summary
Rocky Mountain spotted fever encephalitis can affect the brain, causing specific changes on MRI scans. These abnormalities resolved as the patient
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Rocky Mountain spotted fever (RMSF) is a tick-borne illness.
- Encephalitis is a serious complication of RMSF.
Observation:
- A case of RMSF encephalitis is presented.
- Brain magnetic resonance (MR) imaging was performed.
Findings:
- MR examination revealed increased signal intensity in the perivascular spaces.
- These MR abnormalities resolved with clinical improvement.
Implications:
- This case highlights the neuroimaging findings in RMSF encephalitis.
- Perivascular space involvement may be a characteristic finding.
- MR imaging can monitor treatment response in RMSF encephalitis.
