How is an epidural hematoma diagnosed?

If your doctor suspects you have an epidural hematoma, they can use a variety of tests to diagnose and locate it. For example, they may order: neurological tests. computed tomography (CT) scans or magnetic resonance imaging (MRI) to examine your skull and the soft tissue in your brain.

How do you remember epidural or subdural?

A subdural hematoma is concave like a banana. You can use the “B” in suBdural to remember Banana. An epidural hematoma is convex like a lemon. You can rearrange the letters in “EPI” to make “PIE” to help you remember lemon PIE.

How does an extradural hematoma appear on CT?

CT. In almost all cases, extradural hematomas are seen on CT scans of the brain. They are typically bi-convex (or lentiform) in shape, and most frequently beneath the squamous part of the temporal bone. EDHs are hyperdense, somewhat heterogeneous, and sharply demarcated.

Why is there lucid interval in epidural hematoma?

Indications. When related to haemorrhage, the lucid interval occurs after the patient is knocked out by the initial concussive force of the trauma and then temporarily recovers, before lapsing into unconsciousness again when bleeding causes the haematoma to expand past the extent for which the body can compensate.

Which is worse a subdural or epidural hematoma?

Because of associated brain injuries and complications of secondary injury, the outcome of subdural hematoma is worse than that of epidural hematoma in children. Surgical intervention may be necessary, especially with large subdural hematomas causing a mass effect.

What is the difference between subdural and epidural hematoma?

An epidural hematoma lies outside (on top) of the dura mater (epi is Greek for upon), while a subdural hematoma lies inside (beneath) the dura mater (sub is Greek for below) and outside the arachnoid mater.

Can you recover from epidural hematoma?

In adults, most recovery occurs in the first 6 months. Usually there is some improvement over 2 years. If there is brain damage, full recovery isn’t likely.

Do all epidural hematomas need surgery?

Not all cases of acute EDH require immediate surgical evacuation. If a lesion is small and the patient is in good neurological condition, observing the patient with frequent neurological examinations is reasonable.

What can cause an epidural hematoma?

An epidural hematoma (EDH) occurs when blood accumulates between the skull and the dura mater, the thick membrane covering the brain.

• They typically occur when a skull fracture tears an underlying blood vessel.
• EDHs are about half as common as a subdural hematomas and usually occur in young adults.

How does an epidural hematoma affect the body?

An epidural hematoma affects the body within minutes of a head injury. As the ruptured blood vessel bleeds onto the brain, the blood pocket places pressure on the brain causing it to swell. As a result, a person may experience headache, dizziness, and confusion . The headache may disappear and return several hours later.

What causes spinal epidural hematoma?

Spinal epidural hematoma Trauma is a common cause of spinal epidural hematoma. Trauma is a common cause of spinal epidural hematoma. Non-trauma causes include anticoagulant therapy, hemophilia , liver disease, aspirin use, systemic lupus erythematosus, and, rarely, lumbar puncture.

How common is an epidural hematoma?

Epidural hematomas occur in up to 3% of all children hospitalized for traumatic head injury. They usually occur secondary to impact injury from a fall.

Where are epidural hematomas ussually seen?

Epidural hematoma occurs between the skull and the dura mater . It is most commonly seen after trauma and fracture to the temporal bone, which results in the rupture of the middle meningeal artery. CT scan of the bleed will demonstrate biconvex, hyperdense, lentiform appearance that does not cross suture lines.
