[Temporal lobe epilepsy. Aetiological classification in 61 paediatric patients].

INTRODUCTION
There are very few studies on the aetiology of temporal lobe epilepsy (TLE) in childhood. The purpose of the present study is to analyse the data of 61 children diagnosed with TLE, in order to describe the aetiology of TLE in children seen in a neuropaedriatic clinic. We also discuss the currently proposed classification.


PATIENTS AND METHODS
A retrospective analysis was carried out on patients diagnosed with TLE. Patients consisted of 61 children less than 15 years old.


RESULTS
Patients were classified into three groups: Group 1 (symptomatic temporal lobe epilepsy) consisted of 25 patients (40.98 %) with any temporal lesion on neuroimaging (tumours, malformations or infections) or significant history; Group 2 (Mesial temporal sclerosis) consisted of 17 patients (27.86 %), a history of simple and complex febrile seizure were common in this group; and Group 3 (Cryptogenic epilepsy) consisted of 19 patients (31.15 %) with no abnormalities on neuroimaging or significant history.


CONCLUSION
To our knowledge, this is the largest paediatric series of childhood new-onset TLE assessed only by MRI in the literature. We have modified the previous aetiological classification in order to make the groups more realistic.
