We examined the relationship between presence and frequency of different types of auras and side of lesion and post surgical outcomes in 205 patients with medically intractable mesial temporal lobe epilepsy (MTLE) with unilateral hippocampal sclerosis (HS). With respect to the number of auras, multiple auras were not associated with side of lesion (p=0.551). the side of HS was not associated with the type of auras reported. One hundred fifty-seven patients were operated. the occurrence of multiple auras was not associated with post-surgical outcome (p=0.740). the presence of extratemporal auras was significantly higher in patients with poor outcome. in conclusion, this study suggests that the presence of extratemporal auras in patients with MTLE-HS possibly reflects extratemporal epileptogenicity in these patients, who otherwise showed features suggestive of TLE. Therefore, TLE-HS patients undergoing pre-surgical evaluation and presenting clinical symptoms suggestive of extratemporal involvement should bemore extensively evaluated to avoid incomplete resection of the epileptogenic zone.
