Paradoxical lateralization of parasagittal sharp waves in a patient with epilepsia partialis continua.
We present a patient with epilepsia partialis continua involving the right leg who demonstrated sharp waves paradoxically distributed over the vertex and right hemisphere. Posterior tibial nerve evoked potentials also showed a similar paradoxical lateralization. We postulate that generators situated on the mesial surface of the left hemisphere projected their activity obliquely, leading to paradoxical lateralization of the recorded electrical activity.
