case_images: Several irregular slow waves with medium to high amplitudes were recorded in the right temporal leads, which spread to other leads and showed sharp waves (shown by the red arrow).

case_images: The electroencephalography (EEG)showed irregular slow waves with medium to high amplitudes in the right temporal lobe, which spread to the other lobes and showed sharp waves (Figure 1).
case_images: (A) Increased signal intensity was seen on the T2-weighted FLAIR imaging in the right medial temporal lobe (shown by the red arrow). (B) Gadolinium-enhanced MRI of the brain showed mild to moderate cord enhancement in the right temporal lobe (shown by the red arrow). (C) The brain MRA did not show vascular stenosis or vasculitis-like changes. (D) The increased signal intensity on T2-weighted FLAIR imaging in the right medial temporal lobe disappeared after syphilitic treatment.

case_images: T2-weighted and FLAIR imaging in the medial temporal lobe (Figure 2A). The gadolinium-enhanced MRI of the brain showed mild to moderate cord enhancement in the right temporal lobe (Figure 2B). However, the results revealed no abnormalities (Figure 2C). Moreover, a repeat of the brain MRI showed no abnormality (Figure 2D).
case_images: A repeat of the EEG showed no irregular slow waves and sharp waves emission. *** means uV, the unit of measurement of electromyography (EMG).

case_images: In addition, a repeat of the EEG showed no epileptiform wave emission (Figure 3).
