Abstract:
Two cases of tuberculous meningoencephalitis mimicking regressive or transient ischaemic attacks or migraine with aura are reported. The value of MRI with gadolinium in demonstrating inflammation of the leptomeninges, of transcranial Doppler sonography in detecting segmentary accelerations in the basal cerebral arteries suggestive of arteritis and of CSF examination with polymerase chain reaction (PCR) are emphasized.
Insights
Tuberculous meningoencephalitis can mimic transient ischemic attacks or migraines. Advanced imaging and cerebrospinal fluid analysis are crucial for accurate diagnosis of this rare condition.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Tuberculous meningoencephalitis is a rare but serious central nervous system infection.
- Early diagnosis is critical to prevent severe neurological sequDoppler and cerebrospinal fluid (CSF) analysis with polymerase chain reaction (PCR) are valuable diagnostic tools.
Observation:
- Two cases are presented where tuberculous meningoencephalitis mimicked other neurological conditions like transient ischemic attacks or migraine with aura.
- The clinical presentation posed a diagnostic challenge.
Findings:
- Magnetic resonance imaging (MRI) with gadolinium contrast effectively visualized leptomeningeal inflammation.
- Transcranial Doppler (TCD) sonography revealed segmental accelerations in basal cerebral arteries, suggesting arteritis.
- CSF examination using PCR confirmed tuberculous meningitis.
Implications:
- These findings highlight the importance of considering tuberculous meningoencephalitis in the differential diagnosis of stroke-like or migraine presentations.
- Integrated use of advanced neuroimaging (MRI, TCD) and molecular diagnostics (PCR) improves diagnostic accuracy for CNS tuberculosis.
- Prompt diagnosis and treatment are essential to improve patient outcomes and prevent long-term neurological deficits.
