Neurosurgery Oral Board Practice Cases by Domain
Build broad general-rotation readiness, then add focus-area depth and personal-case defense. Each domain should include diagnosis, operation, deterioration, and follow-up—not just classic presentations.
Key takeaways
- The published ABNS focus areas are Spine, Tumor/Neuro-oncology, Vascular, Functional, Pediatric Neurosurgery, and General.
- General-rotation preparation should also include trauma/critical care, infection, hydrocephalus, peripheral nerve, and perioperative complications.
- Practice each domain across four modes: initial diagnosis, operative defense, complication rescue, and longitudinal follow-up.
- Personal cases form a separate practice domain because exact facts and ownership matter.
Use a four-mode coverage model in every domain
| Mode | Question the practice case should force |
|---|---|
| Recognition | Can you identify the syndrome, localize, prioritize the dangerous alternative, and choose the next discriminating step? |
| Decision | Can you defend observation, procedure, surgery, timing, alternatives, and patient selection? |
| Technique | Can you describe the approach, critical anatomy, sequence, safeguards, and bailout plan? |
| Rescue & follow-up | Can you recognize deterioration, rescue the patient, and own postoperative care and surveillance? |
General neurosurgery
Core coverage
Hydrocephalus and shunt problems, infection, CSF disorders, common cranial and spinal emergencies, peripheral nerve, pain, perioperative management, and cross-domain complications.
High-value branch
The patient’s neurologic examination worsens after the initial plan. State what you stop, what you reassess, the fastest decisive evaluation, and the rescue threshold.
Technical prompt
Describe the procedure in a way that makes the operative goal, critical anatomy, and failure modes explicit.
Spine
Core coverage
Degenerative cervical and lumbar disease, deformity, trauma, tumor, infection, instability, junctional and hardware complications, and postoperative neurologic decline.
Decision prompt
Why is surgery indicated, what decompression and stabilization are required, and what feature would change the approach or extent?
Rescue prompt
A new deficit appears after surgery. Walk through immediate examination, physiologic optimization, imaging or return-to-OR threshold, and definitive management.
Tumor / Neuro-oncology
Core coverage
Primary and metastatic lesions, extra-axial tumors, sellar/skull-base disease, spinal oncology, tissue diagnosis, adjuvant therapy, surveillance, recurrence, and treatment morbidity.
Decision prompt
Define the goal—diagnosis, decompression, cytoreduction, durable control, or palliation—and explain how functional anatomy and systemic disease alter the plan.
Outcome prompt
Integrate pathology, molecular data when relevant, postoperative imaging, neurologic function, adjuvant therapy, and recurrence strategy.
Vascular
Core coverage
Hemorrhage, aneurysm, arteriovenous malformation/fistula, ischemic disease, revascularization, vascular injury, perioperative stroke, and treatment complications.
Decision prompt
State urgency, vascular anatomy, open/endovascular/observational alternatives, treatment goal, and how patient/lesion factors change risk.
Rescue prompt
The patient deteriorates during or after treatment. Prioritize hemorrhage, ischemia, pressure, seizure, hydrocephalus, and treatment-related mechanisms.
Functional
Core coverage
Movement disorders, epilepsy surgery principles, neuromodulation, pain/spasticity, patient selection, target confirmation, hardware, infection, programming, and neuropsychological considerations.
Selection prompt
What makes the patient an appropriate candidate, what multidisciplinary evaluation is required, and which expectation would make you defer intervention?
Complication prompt
Differentiate hardware, target, stimulation, medication, hemorrhagic, infectious, and disease-progression causes of a poor result.
Pediatric neurosurgery
Core coverage
Hydrocephalus, congenital malformations, craniosynostosis principles, pediatric tumors, dysraphism, trauma, epilepsy, infection, and age-specific perioperative care.
Age-specific prompt
Explain how age changes physiology, examination, imaging, blood loss tolerance, timing, family counseling, and long-term developmental follow-up.
Family prompt
Communicate uncertainty, treatment goals, expected neurologic/developmental outcomes, and longitudinal surveillance to caregivers.
Trauma and neurocritical care
Trauma/critical care is a SurgiTest catalog domain and an essential component of broad general-neurosurgery preparation; it is not listed as a separate focus-area option on the current ABNS public page.
Core coverage
Initial stabilization, intracranial and spinal injury, monitoring, mass lesions, anticoagulation/reversal, polytrauma priorities, secondary injury prevention, and goals-of-care decisions.
Prioritization prompt
State what must happen in the first minute, what can occur in parallel, and what finding triggers immediate operation or transfer.
Longitudinal prompt
Address ICU goals, serial examination/imaging, seizure and VTE considerations, nutrition, tracheostomy/feeding discussions, rehabilitation, prognosis, and family communication as relevant.
Personal-case domain
Your submitted cases are not interchangeable with catalog cases. Practice must be grounded in the actual indication, imaging, operation, pathology, outcome, and complications of the case you performed.
- Defend the indication and timing.
- Describe the operation without notes.
- State the exact intraoperative finding that changed management.
- Own complications and rescue decisions.
- Give the last meaningful follow-up accurately.
- Explain what you would do differently and why.

Put the framework under pressure
Practice the answer out loud—not only on paper.
Voice-first cases, adaptive examiner follow-up, imaging, complications, and structured educational feedback for neurosurgery.
Questions candidates ask
Frequently asked questions
Which focus areas does ABNS currently publish?
The current public list is Spine, Tumor/Neuro-oncology, Vascular, Functional, Pediatric Neurosurgery, and General.
Should I practice only my selected focus area?
No. The examination also includes a general-neurosurgery rotation and a rotation based on selected submitted cases. Focus-area depth should sit on top of broad safety and management readiness.
How do I know whether coverage is adequate?
Track whether each domain has been practiced in recognition, treatment-decision, operative-technique, and complication/follow-up modes. Repeated cases in one mode do not replace missing modes.
