Magnetic resonance imaging in drug-induced meningitis
Abstract:
Pathologic meningeal enhancement has been reported in patients with bacterial and viral meningitis. The authors describe a 52-year-old woman with drug-induced aseptic meningitis in whom diffuse meningeal enhancement was observed with magnetic resonance imaging after administration of gadolinium diethylenediaminepenta-acetic acid. The cause and mechanism of drug-induced aseptic meningitis and the value of magnetic resonance imaging in the diagnosis of this uncommon condition are stressed.
Insights
Magnetic resonance imaging revealed diffuse meningeal enhancement in a patient with drug-induced aseptic meningitis. This case highlights MRI
Area of Science:
- Neurology
- Radiology
- Pharmacology
Background:
- Meningeal enhancement on MRI is typically associated with infectious meningitis (bacterial, viral).
- Drug-induced aseptic meningitis is an uncommon condition.
- Gadolinium-based contrast agents are used in MRI to improve visualization of certain tissues and abnormalities.
Observation:
- A 52-year-old woman presented with symptoms suggestive of meningitis.
- Following administration of gadolinium diethylenediaminepenta-acetic acid for magnetic resonance imaging, diffuse meningeal enhancement was observed.
- The patient was diagnosed with drug-induced aseptic meningitis.
Findings:
- Diffuse meningeal enhancement on MRI can occur in drug-induced aseptic meningitis, not solely infectious causes.
- Magnetic resonance imaging (MRI) with gadolinium contrast is valuable in diagnosing this condition.
- The specific cause and mechanism of drug-induced aseptic meningitis were investigated.
Implications:
- This finding expands the differential diagnosis for meningeal enhancement on MRI.
- Highlights the importance of considering drug reactions in aseptic meningitis.
- Emphasizes the utility of advanced neuroimaging in diagnosing rare neurological conditions.
