Note: This is actually a CT scan (not an X-ray), specifically a Non-Contrast CT (NCCT) of the head. Here is the full analysis:
CT Head - Detailed Radiological Analysis
Modality & Technique
- Type: Non-Contrast CT (NCCT) of the brain
- Plane: Axial slices, arranged from the vertex (top left) down to the skull base and posterior fossa (bottom right)
- Convention: Left side of image = patient's right; right side = patient's left
Key Finding: Acute Right-Sided Subdural Hematoma (SDH)
The most prominent and significant finding is a large, hyperdense (bright white), crescent-shaped extra-axial collection tracking along the right frontoparietal convexity (inner skull surface). This is the hallmark appearance of an acute subdural hematoma.
- Hyperdense = the collection appears bright white, indicating fresh/acute blood (typically <72 hours old)
- The shape is concavo-convex / crescent-shaped, spreading freely over the hemisphere (not limited by suture lines, unlike epidural hematomas)
- The collection is most prominent in the upper and mid-cerebral slices (rows 2-3)
Mass Effect (Signs of Brain Compression)
The hematoma is large enough to exert significant pressure on brain structures:
| Finding | Description |
|---|---|
| Sulcal effacement | Right-sided cerebral sulci are compressed and flattened |
| Right lateral ventricle compression | Ipsilateral ventricle is partially collapsed |
| Leftward midline shift | Septum pellucidum and midline structures are displaced to the left |
| Basal cistern crowding | The cisterns around the brainstem show effacement, suggesting early transtentorial herniation |
Ventricular System
- Right lateral ventricle: Compressed by the overlying hematoma
- Left lateral ventricle: Patent but mildly distorted/dilated from the transmitted pressure
Posterior Fossa (Lower Rows)
- Skull base, cerebellum, brainstem, sphenoid sinuses, and mastoid air cells are visible in the inferior slices
- No obvious large cerebellar hemorrhage or posterior fossa extra-axial collection identified
Bone Windows
- No clearly displaced skull fracture visible on soft-tissue views; a dedicated bone window review would be needed to rule out underlying fractures (which are associated with SDH in trauma)
Overall Impression
Acute right frontoparietal subdural hematoma (SDH) with significant mass effect, including sulcal effacement, right lateral ventricular compression, and leftward midline shift.
This is a neurosurgical emergency. Depending on the thickness of the hematoma, degree of midline shift (typically >5 mm is a surgical threshold), and the patient's neurological status (GCS), urgent surgical evacuation (craniotomy or burr-hole drainage) is likely indicated.

Can EDH Be Treated with a Burr Hole?
Short answer: Not ideally - but yes, as a life-saving temporizing measure when craniotomy is unavailable.
Standard Treatment: Craniotomy
Both Schwartz's Principles of Surgery and the Sabiston Textbook of Surgery are clear:
"Epidural and subdural hematomas are treated similarly with a formal craniotomy centered on the clot, rather than a burr hole."
- Sabiston Textbook of Surgery, p. 804
Criteria for emergent craniotomy in EDH:
- Volume >30 mL
- Associated neurologic deficits
- Radiographic midline shift or effacement of basal cisterns
Craniotomy is preferred because:
- EDH is typically caused by arterial bleeding (middle meningeal artery) - a burr hole cannot adequately control arterial hemorrhage
- A craniotomy gives full exposure to identify and ligate the bleeding vessel
- Burr holes are too small to fully evacuate a clot and provide hemostasis
When Burr Hole IS Acceptable for EDH
A burr hole is used only as a temporizing/life-saving emergency measure in very specific situations:
| Scenario | Detail |
|---|---|
| No neurosurgeon available | General surgeons in communities without neurosurgical coverage should know burr hole technique for life-threatening EDH |
| Polytrauma patient in OR | If the patient is undergoing laparotomy/thoracotomy and has a fixed, dilated pupil suggesting herniation - an exploratory burr hole may be done concurrently |
| CT unavailable, comatose patient | If imaging is unavailable and the patient has decerebrate/decorticate posturing unresponsive to mannitol/hyperventilation |
"General surgeons...should have a working knowledge of burr hole placement in the event that emergent evacuation is required for a life-threatening epidural hematoma...After stabilization, the patient is transferred to a facility with neurosurgical capability for formal craniotomy."
- Schwartz's Principles of Surgery, p. 245
Key Rule for Burr Hole in EDH
- The burr hole is made on the side of the dilated (fixed) pupil (ipsilateral to the hematoma)
- It is only a bridge to definitive craniotomy - not a standalone treatment
- EDH requires evacuation within 70 minutes of clinical deterioration - time is critical
Summary
| EDH | |
|---|---|
| Preferred surgery | Craniotomy |
| Burr hole role | Emergency temporizing only |
| Why not burr hole alone | Cannot control arterial bleed; inadequate clot evacuation |
| Time window | Evacuation within 70 minutes |
