[Visualization of epileptic foci using 99mTc-HM-PAO in SPECT].

A case of a 16 year old female patient with complex partial seizures has been presented. At the beginning of the illness the seizure focus had been located on the left temporal region according to the EEG finding and the clinical manifestation. Later on the epileptic focus changed sides to the right temporal region. The CT finding of this patient had been normal and the SPECT-HM-PAO method revealed a significant reduction of rCBF in the parietotemporal region of the left hemisphere, as well as the existence of a region of hyperperfusion in the right temporal lobe.
