Abstract
We describe a patient with seizures following a stroke in whom on ictal Tc- 99m-HMPAO single-photon emission computed tomography demonstrated cerebral blood flow "schistotaxis", i.e., focal hyperaemia corresponding to an epile ptogenic focus together with an extensive hypoperfused area in the same hem isphere. This phenomenon may have been caused by haemodynamic alternation a nd a remote transneural effect during the seizures.
