Quick Summary: What is a Traumatic Subarachnoid Hemorrhage (tSAH)?
A traumatic subarachnoid hemorrhage is a life-threatening brain injury involving bleeding into the space between the brain and its surrounding membrane. In Virginia, these are most commonly caused by high-impact truck crashes, car accidents, falls, and violent assaults. Unlike spontaneous bleeds, a tSAH results from physical shearing forces that tear blood vessels during a collision.
The crash happened in seconds. Maybe it was on I-81 near Harrisonburg, or I-64 outside Charlottesville, or I-95 south of Richmond. A tractor-trailer ran a red light. A driver crossed the center line. You hit your head — or maybe you didn’t hit anything, but the violent force of the impact whipped your head forward and back.
At the hospital, the CT scan showed bleeding around your brain. The doctor used words you’d never heard before: Subarachnoid. Hemorrhage. They admitted you. The medical staff monitored you closely. They may have told you that you were lucky — that it wasn’t worse.
But here’s what nobody told you: This injury can have long-term consequences that are frequently missed, frequently minimized by insurance companies, and frequently undercompensated in personal injury cases. Our Charlottesville brain injury lawyer team understands that and is here to change that.

What Is a Traumatic Subarachnoid Hemorrhage?
Your brain is surrounded by three layers of protective tissue called meninges. The space between the innermost two layers — the arachnoid and the pia mater — is called the subarachnoid space. This space is filled with cerebrospinal fluid, which cushions and protects your brain.
When trauma ruptures the small blood vessels in this space, blood leaks into the cerebrospinal fluid. That is a subarachnoid hemorrhage.
The Two Primary Types of Hemorrhage
- Spontaneous: Caused by a ruptured aneurysm or medical condition.
- Traumatic (tSAH): Caused by external force, such as a vehicle crash.
Traumatic subarachnoid hemorrhage is one of the most common findings on CT scans in patients who have suffered significant head trauma. It ranges from minor bleeds that resolve with monitoring to severe hemorrhages that cause permanent disability or death.
How Do Truck and Car Accidents Cause This Injury?
The subarachnoid space contains tiny bridging blood vessels. These vessels are vulnerable to the shearing and tearing forces that occur when the head accelerates, decelerates, or rotates violently — exactly what happens in a serious crash.
You don’t have to strike your head on anything. The forces of a high-speed collision alone can rupture these vessels. This is especially true in:
- Truck accidents: The mass differential between an 80,000-pound commercial vehicle and a passenger car generates enormous crash forces.
- Rear-end collisions: Sudden forward-then-backward motion creates violent rotational forces.
- Rollover accidents and T-bone accidents: Lateral impact causes rapid side-to-side movement.
This is one reason why truck accident cases involving brain injuries tend to produce more severe hemorrhages than typical car crashes. The physics are simply more destructive. Our Charlottesville car accident lawyer team understands these differences.
Critical Symptoms: What Does a Subarachnoid Hemorrhage Feel Like?
The classic presentation of a subarachnoid hemorrhage is a sudden, severe headache — often described as “the worst headache of my life.” But in traumatic cases, that headache may be masked by or confused with other crash injuries, adrenaline, or the chaos of the immediate aftermath.
Symptoms to watch for after any significant head trauma include:
- Sudden severe headache
- Neck stiffness or pain
- Sensitivity to light (photophobia)
- Nausea and vomiting
- Confusion or altered consciousness
- Loss of consciousness, even briefly
- Seizures
- Blurred or double vision
- Difficulty speaking
If you experience any of these symptoms after a crash — especially a sudden severe headache — seek emergency care immediately. This is a medical emergency. Time matters.
One of the most dangerous aspects of tSAH is that some patients feel relatively normal immediately after injury, only to deteriorate hours or days later as complications develop. Never assume you are fine without a medical evaluation.
Complications: Why This Injury Can Get Worse After the Hospital
A subarachnoid hemorrhage does not always end when the bleeding stops. Several serious complications can follow:
Vasospasm.
This is a narrowing of blood vessels in the brain that can occur in the days following a hemorrhage. Vasospasm reduces blood flow to brain tissue and can cause a delayed stroke — meaning the patient survives the initial bleed only to suffer a stroke days later. Vasospasm is one of the leading causes of disability and death following subarachnoid hemorrhage.
Hydrocephalus.
Blood in the cerebrospinal fluid can block the normal circulation and drainage of that fluid, causing it to build up and increase pressure on the brain. This may require emergency surgical intervention.
Rebleeding.
The initial hemorrhage can be followed by additional bleeding, which is often more severe than the first event.
Cognitive and neurological deficits.
Even patients who survive without catastrophic complications frequently experience lasting problems — memory impairment, difficulty concentrating, mood changes, fatigue, and headaches that persist long after discharge. These overlap significantly with the symptoms of post-concussion syndrome, and the two conditions can occur together.
Pituitary dysfunction.
Subarachnoid hemorrhage can damage the pituitary gland, disrupting hormone production in ways that are subtle but profoundly life-altering. We covered this in detail in our article on pituitary gland damage after trauma.

How Is a Traumatic Subarachnoid Hemorrhage Diagnosed?
CT scan is the primary diagnostic tool in the emergency setting and is highly sensitive for detecting subarachnoid blood in the first 24 to 48 hours.
Lumbar puncture (spinal tap) may be used if CT findings are inconclusive — blood or breakdown products in the cerebrospinal fluid confirm the diagnosis.
MRI becomes more useful in the days and weeks following injury, and can reveal associated injuries — diffuse axonal injury, contusions, and other structural damage that CT may miss.
CT angiography may be used to evaluate blood vessels and rule out an underlying aneurysm.
From a legal standpoint, the diagnostic record matters enormously. The timing of imaging, the findings, the follow-up studies — all of this becomes evidence in your claim. Make sure your medical records are complete and preserved.
How Insurance Companies Handle These Claims
You would think bleeding on the brain would be taken seriously by an insurer. However, defense teams often use the following tactics:
- “It was a minor bleed”: Arguing that small bleeds have no long-term consequences (which medical science refutes).
- Disputing Causation: Claiming the bleed was caused by pre-existing high blood pressure or an undiagnosed aneurysm.
- Minimizing Cognitive Impact: Claiming you have “recovered” once you are discharged from the hospital, ignoring lasting memory loss or fatigue.
- The gap in treatment argument. If you didn’t follow up with a neurologist, a neurosurgeon, or a rehabilitation specialist, expect that gap to be used against you. Follow your treatment plan. Document everything.

Frequently Asked Questions
| Question | Answer |
| Subarachnoid vs. Subdural? | Subarachnoid is bleeding in the fluid-filled space around the brain; Subdural is a clot pressing on the brain. Both are critical. |
| Can I have a tSAH without losing consciousness? | Yes. You do not need to “black out” to have sustained a serious brain bleed. |
| What is the statute of limitations in Virginia? | Generally, you have two years from the date of the accident (or death) to file a claim. |
What a Virginia Subarachnoid Hemorrhage Claim Can Be Worth
Every case is different. But several factors drive the value of a tSAH claim in Virginia:
Severity and complications.
A hemorrhage that required surgical intervention, caused a stroke, or produced lasting neurological deficits is worth significantly more than one that resolved with monitoring alone.
Long-term functional impact.
Can you return to your job? Your prior level of activity? Your relationships? Loss of earning capacity and loss of enjoyment of life are major components of catastrophic injury damages in Virginia.
Future medical needs.
Patients who require ongoing neurology care, rehabilitation, or monitoring for complications are entitled to have those future costs documented and recovered. A life care plan prepared by a certified specialist is often essential in cases of this severity.
Who caused the crash.
When a commercial trucking company is responsible, the damages picture changes significantly. Commercial carriers are required to carry substantially higher insurance limits than private drivers. And trucking companies — and their insurers — have experienced defense teams working the case from day one. You need experienced representation to match that.

The Bottom Line About Subarachnoid Hemorrhages
A traumatic subarachnoid hemorrhage is not a minor injury with a minor outcome. It is bleeding on the brain, caused by someone else’s negligence, with potentially life-altering consequences.
Virginia law gives you the right to be fully compensated for what happened to you. But that compensation doesn’t come automatically. It comes from building a complete medical record, fighting the insurance company’s tactics, and having experienced legal representation that understands both the medicine and the litigation.
