Neuroimaging of Rasmussen's encephalitis

Area of Science:

• Neurology
• Pediatrics
• Neuroimmunology

Background:

• Rasmussen's encephalitis is a rare, chronic inflammatory neurological disease affecting one cerebral hemisphere.
• It primarily impacts children, leading to progressive neurological deficits.

Observation:

• A 5-year-old child presented with focal seizures and progressive hemiparesis.
• Symptoms evolved over a 2.5-year period, indicating a chronic and worsening condition.

Findings:

• Neuroimaging revealed progressive atrophy of the right temporal lobe.
• This atrophy correlated with the observed clinical decline.

Implications:

• The case highlights the importance of integrating clinical presentation with neuroimaging for diagnosing Rasmussen's encephalitis.
• Timely diagnosis can potentially guide early therapeutic interventions, although the condition is often refractory.
