Utilidad del PET en la epilepsia no lesional del lóbulo temporal / Usefulnes of PET scan in non-lesional related temporal lobe epilepsy

ABSTRACT

Objective: to evaluate the usefulness of PET in patients with refractory non-lesional temporal lobe epilepsy. Material and methods: we present three patients with features of temporal lobe epilepsy refractory to medication, where highdefinition MRI was normal. Results: these patients had PET hypometabolism in the temporal areas related to clinical and neurophysiological findings. Two of these patients were implanted with subdural grids to confirm the diagnosis and the third was operated directly based on the findings of PET. Encourage the presentation of the importance in recent years is acquiring the PET. Conclusion: in those patients in clinical neurophysiology and epilepsy with suspected temporal lobe, but in the MRI images show no structural lesions, PET can play an important role defining the diagnosis.
