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.

A—interictal discharges from implanted intracranial ECoG. Some spikes were detected inside the lesion area (black arrow), but the amplitude of spikes was higher in the adjacent areas of the lesion (red arrow). B—no ripple fast rhythm or obvious discharges except isolated spikes before seizure, performed as left hand clonus (the upright blue line marked seizure beginning observed by video as right hand clonus).

B—no ripple fast rhythm or obvious discharges except isolated spikes before seizure, performed as left hand clonus (the upright blue line marked seizure beginning observed by video as right hand clonus).

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).
