Figure 12.10

Typical absence seizures of late onset due to frontal lobe glioma.

Left: Brain imaging showing a right-sided frontal glioma in a woman who started having absences at 28 years of age (1989). Middle right and left: Initially, the EEG GSWD were entirely symmetrical; there was nothing to suggest that these were symptomatic absences. Clinically, during the GSWD, the woman made minor and occasional errors on breath counting, with consistent eyelid flickering. In her daily life, these were manifested as “losing control of thoughts, repeating simple phrases and occasional mild jerking of the head to the right”. This could last for a few seconds to a minute and once she had non-convulsive status epilepticus with mild confusion and expressive dysphasia. Right: Video EEG 6 years later showed that she continued to have similar GSWD with right-sided asymmetry
