Surgical resection of epileptogenic cortical dysplasia in precentral gyrus.

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—lesion seen in operation. The lesion had a slightly different color and solid texture compared with normal cortices (yellow circle), vein was slightly pushed backward (black arrow). B—electrode grid implanted surrounding the lesion and covering the whole central area.

f0015: A—lesion seen in operation. The lesion had a slightly different color and solid texture compared with normal cortices (yellow circle), vein was slightly pushed backward (black arrow). B—electrode grid implanted surrounding the lesion and covering the whole central area.

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).
