Schizencephaly is a congenital malformation of the cerebral hemispheres, with communication between the lateral ventricle and the subarachnoid space. Marinelli reported that schizencephaly may be associated with continuous involuntary hand movements, such as dystonia or epilepsia partialis continua (EPC). We describe a young Chinese patient with continuous involuntary movements of the contralateral hand affected by schizencephaly. He has a normal scalp electroencephalogram (EEG) but abnormal intracranial EEG, with synchronized periodic lateralized epileptiform discharges. The results obtained from these EEG investigations and the clinical features of the involuntary movements are in favor of a diagnosis of secondary EPC.
脑裂畸形是一种先天性大脑半球畸形，其特征是侧脑室与蛛网膜下腔相通。Marinelli 报道脑裂畸形可能与手部持续性不自主运动相关，如肌张力障碍或部分性持续癫痫（EPC）。我们描述了一例年轻的中国患者，其手部出现持续性不自主运动，受脑裂畸形影响。患者头皮脑电图（EEG）正常，但颅内 EEG 异常，表现为同步周期性偏侧癫痫样放电。这些 EEG 研究结果和不自主运动的临床特征均支持继发性 EPC 的诊断。
