Acute measles encephalitis of the delayed type
Abstract:
An acute measles encephalitis with epilepsia partialis continua occurred three months after measles in a previously healthy child with no detectable immunological defect. Levels of measles antibodies in serum and cerebrospinal fluid were high, and tubular inclusions of the type seen in subacute sclerosing panencephalitis were found in nerve cell nuclei. A communicating high-pressure hydrocephalus developed in the later stage of the disease. This case demonstrates that measles encephalitis of the delayed type should systematically be considered in children with acute encephalitis.
Insights
Delayed measles encephalitis can occur months after infection, even in healthy children. This condition, marked by seizures and neurological changes, requires careful consideration in diagnosing acute encephalitis.
Area of Science:
- Neurology
- Pediatrics
- Infectious Diseases
Background:
- Measles infection can lead to severe neurological complications.
- Delayed-onset encephalitis following measles is a rare but serious condition.
Observation:
- A previously healthy child developed acute measles encephalitis with epilepsia partialis continua three months post-measles.
- The child exhibited high measles antibody levels in serum and cerebrospinal fluid.
- Tubular inclusions, typical of SSPE, were observed in nerve cell nuclei.
Findings:
- The case presented with a delayed-onset measles encephalitis, distinct from typical acute presentations.
- Epilepsia partialis continua and high-pressure hydrocephalus were significant clinical features.
- The presence of SSPE-like inclusions suggests a specific pathogenetic mechanism.
Implications:
- This case highlights the importance of considering delayed measles encephalitis in the differential diagnosis of acute encephalitis in children.
- Early recognition and diagnosis are crucial for managing this severe neurological condition.
- Further research into the pathogenesis of delayed measles encephalitis is warranted.
