1A 24-year-old male is brought to the emergency department after a motor vehicle crash. He had an initial brief loss of consciousness, followed by a 2-hour lucid interval. On arrival, his GCS drops from 14 to 7, and he develops an ipsilateral dilated, fixed right pupil and contralateral left hemiparesis. Urgent non-contrast head CT demonstrates a biconvex, hyperdense extra-axial collection in the right temporoparietal region. What is the most likely injured vascular structure and definitive management?
A.Bridging cortical veins; emergent decompressive hemicraniectomy with duraplasty
B.Middle meningeal artery; emergent right pterional or temporal craniotomy with hematoma evacuation
C.Superior sagittal sinus; conservative management with intracranial pressure monitoring
D.Internal carotid artery laceration; emergent balloon occlusion and endovascular stenting
Explanation: This presentation describes the classical clinical picture of an acute epidural hematoma (EDH) resulting from a tear of the middle meningeal artery or its branches, typically associated with a squamosal or temporal bone fracture. The rapid neurological deterioration with ipsilateral uncal herniation (pupillary dilation) and contralateral motor deficit mandates immediate emergent craniotomy and hematoma evacuation to prevent irreversible brainstem compression. Bridging veins are classically torn in acute subdural hematomas, which appear crescentic rather than lentiform/biconvex.
2A 78-year-old female on therapeutic warfarin for atrial fibrillation presents comatose (GCS 6) following a fall. Urgent CT head demonstrates a 16-mm thick hyperdense crescentic extra-axial collection over the left cerebral convexity with 9 mm of midline shift and effacement of the ipsilateral lateral ventricle. Her INR is 3.4. What is the immediate first-line medical intervention prior to transferring the patient to the operating room for emergency craniotomy?
A.Transfusion of 4 units of fresh frozen plasma (FFP) over 4 hours
B.Administration of 4-factor prothrombin complex concentrate (4F-PCC) and intravenous vitamin K
C.Platelet transfusion and intravenous desmopressin (DDAVP)
D.Intravenous tranexamic acid infusion alone
Explanation: In life-threatening intracranial hemorrhage associated with vitamin K antagonist (warfarin) anticoagulation, 4-factor prothrombin complex concentrate (4F-PCC) along with intravenous vitamin K is the gold-standard first-line therapy for rapid INR reversal. 4F-PCC normalizes INR within 15 to 30 minutes with minimal volume loading compared to FFP, allowing safe and immediate surgical evacuation of the acute subdural hematoma without dangerous surgical delays. Fresh frozen plasma takes hours to thaw and infuse and risks volume overload.
3A 32-year-old male with severe traumatic brain injury (post-resuscitation GCS 6) has an intracranial pressure (ICP) monitor inserted. The ICP monitor displays an ICP of 26 mmHg, and his arterial line shows a mean arterial pressure (MAP) of 80 mmHg. What is the patient's cerebral perfusion pressure (CPP), and what is the target CPP range recommended by Brain Trauma Foundation (BTF) guidelines?
A.CPP is 106 mmHg; target CPP range is 100 to 120 mmHg
B.CPP is 54 mmHg; target CPP range is 60 to 70 mmHg
C.CPP is 54 mmHg; target CPP range is 30 to 50 mmHg
D.CPP is 26 mmHg; target CPP range is 40 to 60 mmHg
Explanation: Cerebral perfusion pressure is calculated as MAP minus ICP (CPP = MAP - ICP). Here, CPP = 80 - 26 = 54 mmHg. Brain Trauma Foundation (BTF) guidelines recommend maintaining CPP between 60 and 70 mmHg in adults with severe TBI while avoiding CPP < 60 mmHg (risk of ischemia) or aggressive vasopressor titration to CPP > 70 mmHg (risk of acute respiratory distress syndrome / ARDS).
4A 45-year-old male with severe traumatic brain injury develops refractory intracranial hypertension with ICP persistently exceeding 28 mmHg despite head elevation, sedation, neuromuscular blockade, CSF drainage via an external ventricular drain, and hyperosmolar therapy (serum osmolarity 316 mOsm/L). Brain CT demonstrates diffuse hemispheric swelling with effaced basal cisterns. According to the RESCUEicp trial, what is the next appropriate surgical intervention?
A.Bilateral subtemporal burr holes without dural opening
B.Decompressive hemicraniectomy with expansile duraplasty
C.Lumbar drain placement for continuous CSF drainage
D.Endoscopic fenestration of the lamina terminalis
Explanation: The RESCUEicp trial demonstrated that secondary decompressive craniectomy (a large unilateral hemicraniectomy or bifrontal craniectomy with expansile duraplasty) for refractory traumatic intracranial hypertension significantly reduces mortality compared to ongoing medical therapy. Lumbar drains are strictly contraindicated in the setting of severe intracranial mass effect and effaced basal cisterns due to the risk of precipitating fatal transtentorial or tonsillar herniation.
5An 82-year-old male presents with a 3-week history of progressive confusion, right-sided pronator drift, and gait ataxia. Brain CT shows a large hypodense crescentic extra-axial collection overlying the left frontoparietal cortex measuring 22 mm in depth with 8 mm of midline shift. What is the surgical procedure of choice with the best balance of low recurrence and minimal morbidity?
A.Single or double burr hole craniostomy with closed-system subdural drain placement
B.Wide osteoplastic craniotomy with radical membranectomy under general anesthesia
C.Percutaneous needle aspiration at the bedside without continuous drainage
D.Immediate middle meningeal artery embolization as monotherapy without drainage
Explanation: Burr hole craniostomy (single or double) with irrigation and placement of a closed-system subdural drain left in place for 24 to 48 hours is the gold standard surgical intervention for symptomatic chronic subdural hematoma (CSDH). Randomized controlled trials have established that postoperative subdural drain placement significantly reduces hematoma recurrence rates and mortality compared to burr hole drainage without a drain. Craniotomy with radical membranectomy is associated with higher operative morbidity and is reserved for multi-recurrent or solid organized hematomas.
6A 28-year-old unrestrained driver sustains facial fractures and an anterior skull base fracture following a road traffic collision. On day 2, he develops clear watery drainage from the left nostril that increases when leaning forward. Fluid analysis confirms positive beta-2 transferrin. He is neurologically intact with no signs of meningitis. What is the recommended initial management strategy?
A.Immediate transnasal endoscopic surgical repair of the cribriform plate within 24 hours
B.Prophylactic intravenous ceftriaxone for 14 days and insertion of a nasogastric tube
C.Conservative management with bed rest, head-of-bed elevation (30°), avoidance of nose blowing/straining, and observation for 7 to 10 days
D.Placement of a permanent lumbar peritoneal shunt
Explanation: The majority (over 70-80%) of acute traumatic CSF rhinorrhea cases resolve spontaneously within 7 to 10 days with conservative measures including head-of-bed elevation (30-45°), bed rest, stool softeners, and avoidance of sneezing, nose blowing, or Valsalva maneuvers. Routine prophylactic antibiotics are not recommended by guidelines as they do not prevent meningitis and select for resistant organisms. Surgical repair is indicated if CSF leak persists beyond 10-14 days.
7A 19-year-old male sustains a direct blow to the vertex with a blunt metal rod. Clinical exam reveals a scalp laceration over the right parietal bone. CT head with bone windows demonstrates a compound (open) depressed parietal skull fracture with bone fragments driven 14 mm below the inner table, associated with underlying dural laceration and localized cortical contusion. What is the definitive management?
A.Surgical debridement, elevation of depressed fragments, watertight dural repair, and antibiotic coverage
B.Scalp laceration suturing in the emergency department and observation with outpatient oral antibiotics
C.Application of a closed cranial halo brace without operative intervention
D.Radiation therapy to prevent heterotopic bone formation
Explanation: Open (compound) depressed skull fractures with displacement greater than the thickness of the cranial vault (or > 5-10 mm), dural violation, cortical laceration, significant intracranial hematoma, or gross wound contamination require urgent operative debridement, fragment elevation, inspection and watertight repair of the dura, and intravenous antibiotics to prevent osteomyelitis and intracranial abscess formation.
8A 22-year-old female is admitted comatose (GCS 5) after a high-speed rollover vehicular crash. Initial non-contrast head CT shows small punctate microhemorrhages at the gray-white matter junction and the splenium of the corpus callosum with preserved basal cisterns, out of proportion to her profound coma. Which MRI sequence is most sensitive for detecting and characterizing the extent of diffuse axonal injury (DAI)?
A.T1-weighted non-contrast spin-echo
B.Susceptibility-Weighted Imaging (SWI) or Gradient Recalled Echo (GRE)
C.Proton density weighted imaging
D.MR angiography (MRA) time-of-flight
Explanation: Susceptibility-Weighted Imaging (SWI) and Gradient Recalled Echo (GRE) sequences exploit magnetic susceptibility differences between paramagnetic blood breakdown products (deoxyhemoglobin, methemoglobin, hemosiderin) and surrounding parenchyma. They are extraordinarily sensitive in detecting the punctate petechial microhemorrhages characteristic of diffuse axonal injury (DAI) at the gray-white matter junction, corpus callosum, and dorsolateral brainstem.
9A 35-year-old male with devastating traumatic brain injury is evaluated for brain death. Core body temperature is 37.0°C, systolic blood pressure is maintained at 115 mmHg on low-dose norepinephrine, and CNS depressant drugs have been cleared. All brainstem reflexes are absent. An apnea test is performed with pre-oxygenation (100% FiO2) and baseline PaCO2 of 40 mmHg. After 10 minutes off mechanical ventilation, there are no spontaneous respiratory efforts. What arterial blood gas result confirms a positive apnea test?
A.PaCO2 reaches 45 mmHg with a normal pH of 7.40
B.PaCO2 reaches ≥ 60 mmHg (or ≥ 20 mmHg increase above baseline) with arterial pH < 7.28
C.PaO2 drops below 80 mmHg regardless of PaCO2
D.Serum lactate increases by > 4 mmol/L
Explanation: According to American Academy of Neurology (AAN) and international brain death determination guidelines, a valid and positive apnea test requires the complete absence of spontaneous respiratory effort in the presence of an adequate hypercarbic stimulus: PaCO2 must reach ≥ 60 mmHg (or increase by ≥ 20 mmHg over a normal baseline) accompanied by a resulting acidemia (pH < 7.28).
10A 48-year-old male involved in a high-speed rollover collision sustains non-displaced cervical facet fractures. Screening CT angiography (CTA) of the neck according to Denver criteria demonstrates an intimal flap with luminal narrowing < 25% in the left cervical internal carotid artery (Biffl Grade I blunt cerebrovascular injury). He is neurologically asymptomatic. What is the standard management?
A.Emergent surgical exploration and open carotid patch angioplasty
B.Medical management with antiplatelet therapy (e.g., aspirin) or systemic anticoagulation
C.Immediate endovascular stent placement
D.Observation only without any pharmacological or radiological follow-up
Explanation: Blunt Cerebrovascular Injury (BCVI) Biffl Grade I injuries (intimal irregularity or dissection with < 25% luminal narrowing) are managed medically with antithrombotic therapy (either single/dual antiplatelet therapy or therapeutic heparin) to prevent secondary thromboembolic stroke. Repeat CTA imaging is typically performed at 7 to 14 days to monitor healing or progression. Operative or endovascular interventions are reserved for higher grade lesions, pseudoaneurysms, or failure of medical therapy.
