Fokale kortikale Signaländerungen im diffusionsgewichteten MRT im Rahmen eines fokalen Status epilepticus

Zusammenfassung

Wir berichten über eine 63-jährige Frau mit vorübergehenden, fokal-kortikalen Signalanhebungen im diffusionsgewichteten MRT des Gehirns während eines erstmaligen Status einfach fokaler Anfälle (Epilepsia partialis continua, Kojevnikov-Syndrom). Nach Beendigung des 72 Stunden dauernden Status bildeten sich die Signalanhebungen zurück, es verblieb aber ein kleiner Defekt im Frontalhirn. Wir interpretieren die vorübergehenden fokal-kortikalen Veränderungen als transitorisches Zellödem.

Abstract

We report on a 63-year-old woman showing temporary focal cortical signal changes in diffusion-weighted MRI of the brain during a first status of simple focal seizures (epilepsia partialis continua, Kojevnikov-syndrome). After the status had been ended 72 hours MRI-signal alterations were reversible, yet a small lesion remained in the left frontal brain lobe. We conclude that these temporary focal cortical signal changes are caused by a transient cell edema.
