Sensory Jacksonian seizures triggered by a frontally-located meningioma

Abstract
A patient who presented with sensory Jacksonian seizures and no other clinical symptoms was found to have a meningioma in the premotor area of the frontal lobe. The possibility that brain oedema caused by the tumour encroached on the supplementary motor area and triggered the seizures via cortico-cortical pathways is discussed.
