Rasmussen’s Encephalitis Presenting as Progressive Parietal Dysfunction Sans Seizures

Rasmussen’s encephalitis (RE) is a rare immune-mediated condition that classically presents in children with focal epilepsy or epilepsia partialis continua, progressive hemiplegia associated with cognitive deterioration and chronic unilateral cortical inflammation and hemi-atrophy [1]. Adults may have atypical manifestations including a prolonged prodromal phase, poorly defined residual period and slower progression [2]. Adults have more frequent occipital lobe involvement, bilateral hemispheric involvement or presentation as temporal lobe epilepsy or movement disorders [3].
