Role of Electroencephalography in Presurgical Evaluation of Temporal Lobe Epilepsy

Figure 16

(Case 7) A 42-year-old woman with refractory CPS of suspected insular origin from the age of 32 years with left MTS on MRI. Her seizures would start with an aura as upper limb paraesthesia in about 20% of her seizures that would progress to lack of awareness and profound drooling lasting less than 30 seconds. Interictal EEG showing left temporal theta and left temporal-frontal spikes ((a) arrows and (b) *) ((a) bipolar and (b) referential montage of same epoch). (c) EEG during her recorded seizures showing left temporal rhythmic theta after a brief attenuation for few seconds (c). FDG PET (d) and (e) demonstrate left insular (long arrow) and left mesial temporal (arrow head) hypometabolism ((c) and (d) arrows).
