1. Which one of the following is the most epileptogenic primary brain tumor?
a. DNET/ganglioglioma
b. Glioblastoma
c. Low-grade glioma
d. Meningioma
e. Metastasis
2. Which one of the following types of epilepsy
is LEAST likely to benefit from epilepsy surgery referral?
a. hemimegalencephaly
b. Rasmussen’s syndrome
c. Rolandic epilepsy
d. Sturge-Weber syndrome
e. West syndrome with focal malformation
of cortical development
3. A 37-year-old male with medically refractory
epilepsy undergoes workup for surgery. MRI
shows frontal cortical dysgenesis, and a concordant EEG shows that the seizure focus involves
the posteriorly located motor cortex. Which
one of the following operative approaches
could you consider when seizure activity
extends beyond the area of resection and into
eloquent cortex?
a. Corpus callosotomy
b. Deep brain stimulation
c. Hemispherectomy
d. Multiple subpial transection
e. Vagal nerve stimulation
4. Which one of the following is the best predictor for seizure-free outcome after epilepsy
surgery (assuming total lesionectomy)?
a. Preoperative EEG and MRI concordance
b. Extratemporal seizure focus
c. History of febrile seizures
d. Mesial temporal sclerosis
e. Low grade temporal glioma

5. The frequency of abnormal interictal EEG
findings in the investigation of seizures is
which one of the following?
a. 10-20%
b. 20-30%
c. 30-40%
d. 40-50%
e. 50-60%
6. Which one of the following is most appropriate for predicting postoperative language and
memory impairment in epilepsy surgery
candidates?
a. BOLD functional MRI
b. EEG
c. Hippocampal depth electrodes
d. Ictal SPECT
e. Video telemetry
f. Wada test
7. Neuropsychological testing preoperatively is
unable to:
a. Aid lateralization of the epileptogenic
zone
b. Predict postoperative deficits
c. Assess patients mental reserve capacity
d. Define the epileptogenic zone preoperatively
e. Assess for depression and anxiety
8. Prolonged delay between ictal behavior onset
and first appearance of ictal EEG discharge
during video telemetry (continuous videoEEG recording) is most likely due to:
a. Malfunction of scalp electrodes
b. Drowsy patient
c. Remote/distant site of seizure onset
d. Hyperventilation
e. Withdrawal of antiepileptic medication
9. A 28-year-old male presents with intractable
epilepsy. Sleep EEG is unable to localize the
focus. Coregistered MRI and PET studies
cannot identify an epileptic focus. Subtracted
ictal and interictal SPECT was performed
which showed a hypermetabolic focus in
the left posterolateral temporal lobe. Which
