Xue H, Cai L, Zhang X, Qiao L, Li Y - Epilepsy Behav Case Rep (2013)

Bottom Line: The lesion was resected based on the results of video-ECoG (electrocorticograph) monitoring and electrical cortical stimulation.The patient has been seizure-free for 1 year since operation, and no neurological deficits have been observed.We discuss possible mechanisms of cortical reorganization in this patient and the features of focal cortical dysplasia (FCD) IIb in eloquent cortices.

ABSTRACT
We present the case of a patient with epilepsy arising from cortical dysplasia in his precentral gyrus. The lesion was resected based on the results of video-ECoG (electrocorticograph) monitoring and electrical cortical stimulation. The patient has been seizure-free for 1 year since operation, and no neurological deficits have been observed. We discuss possible mechanisms of cortical reorganization in this patient and the features of focal cortical dysplasia (FCD) IIb in eloquent cortices.

Electrode implantation and result of ECS: No movement functions for the lesion area in the precentral gyrus (yellow circle). The cortex which represents hand movement was shown in red spot. Numbness was felt in the hand and arm when the cortex was electrically stimulated in the blue spot. According to Fig. 4, epileptic discharges were focused in the adjacent cortex surrounding the lesion with higher amplitude (yellow star).

Numbness was felt in the hand and arm when the cortex was electrically stimulated in the blue spot. According to Fig. 4, epileptic discharges were focused in the adjacent cortex surrounding the lesion with higher amplitude (yellow star).

Mentions: We first performed intracranial electrode implantation for video-ECoG monitoring (Fig. 3). Abnormal spike activities and slow wave rhythms were localized at the cortices surrounding the lesion in the patient's left precentral gyrus (Fig. 4). After a 7-day recovery, ECS was conducted with the parameters including pulse width of 0.2 ms, frequency of 50 Hz, and intensity of 1 mA–15 mA, which demonstrated no function in the lesion area; the patient's right hand movement was functionally represented in the postcentral gyrus (Fig. 5).
