The EEG of a 2 1/2-year-old female with a severe cerebral insult showed trifocal periodic lateralized epileptiform discharges (TRIPLEDs). We believe this is the first such record reported. As with BIPLEDs, the physical findings associated with this EEG appear to represent a diffuse cerebral insult. The most frequent causes of BIPLEDs are diffuse anoxic encephalopathy and CNS infection. In this patient, the TRIPLEDs are apparently due to a severe anoxic insult suffered in utero. As is true with BIPLEDs, the presence of TRIPLEDs represents a poor prognosis.
一名患有严重脑损伤的2岁半女性的脑电图显示有三灶性周期性局灶性癫痫样放电（TRIPLEDs）。我们认为这是首次报告的此类记录。与双侧周期性局灶性癫痫样放电（BIPLEDs）一样，与该脑电图相关的体格检查结果似乎代表弥漫性脑损伤。BIPLEDs最常见的原因是弥漫性缺氧性脑病和中枢神经系统感染。在该患者中，TRIPLEDs显然是由于子宫内遭受的严重缺氧损伤所致。与BIPLEDs一样，TRIPLEDs的出现预示着预后不良。
