Abstract

We performed magnetic resonance spectroscopy in three pediatric patients (two boys and one girl, ages 11 to 17 years) with epilepsia partialis continua. Single-voxel proton magnetic resonance spectroscopy was performed on each patient. Data were acquired from voxels of 4 or 8 cm3 from the affected hemisphere and from contralateral homologous regions. The spectral peaks of several metabolites (N-acetyl-aspartate, choline, creatine, and lactate) were measured. Neuropathologic findings revealed Rasmussen's syndrome in two children and gliosis in one. We observed increased lactate-to-creatine ratios and reduced N-acetyl-aspartate-to-creatine ratios in the affected hemispheres in all three children with epilepsia partialis continua. These data support previous reports. The largest increase in the lactate-to-creatine ratio was detected in a patient with Rasmussen's syndrome and ongoing epilepsia partialis continua at the time of measurement. The other two patients had an increase in the lactate-to-creatine ratio and a decrease in the N-acetyl-aspartate-to-creatine ratio in the affected area. The increased lactate-to-creatine ratio was associated with recurrent focal seizures from different underlying pathologies.
