Temporal encephaloceles in epilepsy patients and asymptomatic cases: Size may indicate epileptogenicity

Objective This study was undertaken to identify temporal encephaloceles (TEs) and examine their characteristics in patients with lobe epilepsy (TLE) extratemporal (ETLE), as well asymptomatic cases. Methods Four hundred fifty-eight magnetic resonance imaging scans were examined retrospectively TE 157 TLE, 150 ETLE, 151 healthy controls (HCs). Results At least one identified 9.6% of the TLE (n = 15, 95% confidence interval [CI] 5.3%–15.3%), 3.3% ETLE 5, CI 1.1%–7.6%), 2.0% HCs 3, .4%–5.7%), indicating a significantly higher frequency compared HC subjects (p .027, p .005). Examining TEs both patients, we found that diameter less than 6.25 mm more likely be asymptomatic, sensitivity 91.7% specificity 73.3% (area under curve .867, .723–1.00, .001). Significance Temporal may occur without presenting any clinical symptoms. Patients show groups. According our study, size could used suggest potential epileptogenicity.
