, Module 1. Pre-Surgical Evaluation & Functional
Mapping
1. A 34-year-old patient with drug-resistant focal epilepsy is
undergoing a pre-surgical evaluation. The epilepsy monitoring
team suspects the seizure focus lies within the eloquent cortex of
the dominant hemisphere. Which of the following surgical
interventions would be most appropriate to control seizures while
preserving essential neurological function?
A) Anterior temporal lobectomy
B) Functional brain mapping followed by Multiple Subpial
Transection (MST)
C) Complete hemispherectomy
D) Vagus nerve stimulation (VNS) placement
Correct Answer. B
Rationale. Multiple Subpial Transection (MST) is specifically
designed for epileptogenic zones that overlap with eloquent
cortex (such as language or motor areas). By cutting the
intracortical horizontal fibers while preserving vertical
columns and blood supply, it disrupts seizure propagation
without causing severe functional deficits.
Q2. During a routine pre-operative workup for an intracarotid
amobarbital procedure (WADA test), the interventional radiologist
performs a cerebral angiography. What is the primary clinical
,rationale for conducting this angiogram prior to the injection of the
sedative?
A) To directly map the language center borders before drug
administration
B) To assess arterial blood flow and vascular anatomy to ensure
the drug distributes predictably
C) To determine the exact metabolic rate of glucose uptake in the
temporal lobes
D) To rule out the presence of a subarachnoid hemorrhage
Correct Answer. B
Rationale. Cerebral angiography is necessary prior to WADA
testing to assess cross-filling, vascular anomalies, and
persistent fetal circulation. This ensures the amobarbital
behaves predictably within the target hemisphere and does
not cross over unexpectedly to cause bilateral suppression.
Q3. A patient is undergoing functional mapping via direct cortical
stimulation using a grid electrode. The technologist notes an
expressive aphasia when contacts 33 and 34 are stimulated. In
which anatomical region are these contacts most likely located?
A) Superior temporal gyrus
B) Postcentral gyrus
C) Inferior frontal gyrus
D) Precentral gyrus
Correct Answer. C
, Rationale. Expressive aphasia (Broca's aphasia) occurs due
to disruption or damage to Broca's area, which resides in the
posterior part of the inferior frontal gyrus. Stimulating this
area temporarily suspends the patient's ability to produce
speech.
Q4. A non-invasive imaging modality is chosen to replace the
traditional invasive WADA test for lateralizing language and
memory functions in a patient with temporal lobe epilepsy. Which
test provides this spatial and temporal tracking non-invasively?
A) Interictal SPECT
B) Functional Magnetic Resonance Imaging (fMRI)
C) Positron Emission Tomography (PET)
D) Cerebral Angiography
Correct Answer. B
Rationale. fMRI has significantly decreased the utilization of the
invasive WADA test because it acts as a less invasive alternative
that evaluates blood-oxygen-level-dependent (BOLD) signals
during language and memory tasks to determine cerebral
dominance.
Q5. A 28-year-old male with refractory temporal lobe epilepsy
undergoes an interictal PET scan. The imaging reveals
significantly decreased glucose uptake (hypometabolism) in the
left temporal lobe. What does this metabolic signature typically
signify?
A) An active, ongoing subclinical status epilepticus
