RESUMO
Temporal lobe abnormalities and focal epilepsy have been documented in FGFR3-related clinical condition, including hypochondroplasia and Muenke syndrome. FGFR3 is expressed in the brain during development and could play a role in nervous system development and hippocampal formation. These observations suggest a non-casual association between temporal malformation, epilepsy, and FGFR3 mutations. Herein, we report clinical, electroclinical, and neuroimaging findings of three additional cases of focal epilepsy and temporal lobe malformations occurring in children with FGFR3 gene mutations.

We describe three children with gelastic seizures without hypothalamic hamartoma whose seizures were characterized by typical laughing attacks associated or not with other seizure types. Ictal/interictal EEG and magnetic resonance imaging were performed. All three subjects showed a good response to carbamazepine therapy with complete seizure control in addition to a benign clinical and cognitive outcome. These three cases confirm that gelastic epilepsy without hypothalamic hamartoma, both in cryptogenic or symptomatic patients (one child showed a dysplastic right parietotemporal lesion), usually has a more benign natural history, and carbamazepine seems to be the most efficacious therapy to obtain both immediate and long-term seizure control. These findings need to be confirmed in a larger sample of children affected by gelastic epilepsy without hypothalamic hamartoma.
