Epilepsy - Patient with intractable drop seizures

History
Patient suffered from intractable drop seizures since the age of 18 months.

Original Diagnosis
TMRI showed no abnormalities. Interictal scalp EEG demonstrated epileptiform activity emanating from the right parietal region.

PET Findings
FDG PET scan demonstrated one focal area of cortical hypometabolism in the right posterior parietal region. Ictal EEG demonstrated seizure onset from the right parietal lobe.

Change in treatment plan
The PET abnormality guided the subdural grid placement with very good correlation. The patient was submitted to surgery and is seizure-free.
