Initial electroencephalogram (EEG) (A) showing periodic lateralized discharge (PLED) consisting of triphasic waves over the right temporal region. After treatment with penicillin for 2 courses, PLED disappeared and repeated EEG (B) showed only slowing waves and muscle artifacts produced by persisted rhythmic orofacial involuntary movements (red arrow).

Video-EEG monitoring showed PLEDs consisting of triphasic waves over the right temporal region (Figure 1A). However, Argyll Robertson pupil and rhythmic orofacial involuntary movements persisted after the treatment even at 7-month follow-up (Figure 1B).
