Hemisphere

This CT scan is from an 8-year-old girl who presented with seizures and progressive hemiparesis. The seizures are unilateral and intractable, frequently evolving into focal motor status epilepticus or epilepsia partialis continua. She has been treated unsuccessfully with immunosuppressants. Brain biopsy only shows nonspecific inflammation.

This is Rasmussen’s encephalitis, a rare inflammatory disorder of uncertain pathogenesis.
