A brain hematoma is a type of head injury that occurs when a blood vessel in the brain ruptures and bleeds, causing a mass of clotted blood to form. This can occur due to a traumatic event, such as a car accident or a fall, or it may result from a medical condition, such as a stroke or aneurysm.
Symptoms of a brain hematoma include headache, confusion, weakness on one side of the body, nausea, and seizures.
Brain hematomas are classified according to the area where the bleed has occurred and the amount of pressure exerted on the brain. The most common types of hematomas are epidural, subdural, and intracerebral.
An epidural hematoma occurs when a blood vessel bursts between the skull and the tough outer covering of the brain (the dura mater).
A subdural hematoma occurs when a blood vessel ruptures between the dura mater and the innermost layer of the brain (the arachnoid mater).
An intracerebral hematoma occurs when a blood vessel ruptures within the brain itself.
Treatment for a brain hematoma depends on the bleed's type, size, and location. In mild cases, the patient may be monitored, and medications may be used to reduce swelling and pressure on the brain. Surgery may be necessary to remove the hematoma in more severe cases. Complications from a brain hematoma can include brain damage, paralysis, and death.
It is important to seek medical attention immediately if you suspect a brain hematoma. Early diagnosis and treatment can help reduce the risk of serious complications.
