Objective

In this study the impact of histological subtypes and of dual pathology on the surgical outcome in patients with intractable epilepsy due to focal cortical dysplasia (FCD) was investigated.

Methods

67 patients with FCD underwent retrospective analysis at follow-up periods of 6 to 48 months after epilepsy surgery. Histological subtypes were classified according to Palmini, and seizure outcome according to Engel.

Results

Considering outcome at the last follow-up, Engel Ia was achieved in 63% of patients with mild malformation of cortical development, 67% with FCD1a, 55% with FCD1b, 43% with FCD2a, and 50% with FCD2b. Considering outcome at follow-up periods over 12 and 24 months, Engel Ia was achieved in significantly more patients with FCD1 than with FCD2, and Engel IV occurred most frequently in patients with FCD2a. Outcome in patients with dual pathology was favourable (66% Engel Ia). In all subgroups, no relevant change in outcome was observed over time.

Conclusions

In conclusion, although a predominantly temporal localization of FCD1 may have played a role, a similarly better outcome in FCD1 was also observed in extratemporal epilepsy, suggesting that the histological subtype is at least a cofactor which may influence the postsurgical outcome.
